The inspiration for the white whale Sperm whale life span Moby Dick, sperm whales have the largest heads, biggest brains, and make the Sperm whale life span sound of any animal on Earth. Lofoten, Greenland, Svalbard, Iceland. Sperm whales usually eat a little over kg almost 2, pounds of food per day. To find their prey preferably giant squidthey dive somewhere between and Sperm whale life span, metres and 4, feetthough they can go as deep as 2 km 1. Sperm whale life span average Sperm whale life span lasts about an hour. When hunting smaller fish, sperm whale pods can work together to force feeder Hot sexy ginger teens nude into ball-like clumps that are more substantial to eat than individuals. This includes calling to each other and Sperm whale life span against each other. Males battle for mating rights, then breed with multiple females. The sperm whale pregnancy term lasts about 15 months, resulting in a single calf. The birth is a social event, with the rest of the sperm whale pod forming a protective barrier around Sperm whale life span birthing mother and her calf. Sperm whales have a lifespan similar to humans, living about 70 years. Orcas go after entire sperm whale pods and will try to take a calf or even a female, but the male sperm whales are generally too big and aggressive to be hunted. The North Norway cruise follows the path of more than one kind of whale as it travels amongst the fjords of Troms. The long Norway nights offer travellers on this expedition an excellent chance to take in the beauty and wonder of the Northern Lights. We have a total of 27 cruises with Sperm Whale.

Even with teeth sperm whales are known to commonly swallow their food without biting or tearing apart the flesh of their prey and it is believed that their teeth are not necessary for their survival. In fact sperm whales that have completely lost their teeth or have had deformed jaws have been observed as having perfectly normal and unaffected diets despite their circumstances. When it comes to habitat sperm whales can be found swimming through all of the earths major oceans. Unlike other whale species sperm whales do not appear to stick to a predetermined migration pattern. The blubber layer of sperm whales is quite thick, up to 35 cm. With respect to coloration, males often become paler and are sometimes piebald with age. Both sexes have white in the genital and anal regions and on the lower jaws. The mass of mature sperm whales ranges between 35, 57, kg. Sperm whales are very deep divers and may stay submerged from 20 minutes to over an hour. When they surface, sperm whales typically blow times before descending again. They produce a visible spout made by the condensation of the moisture combined with a mucous foam from the sinuses. Sperm whales typically swim at speeds no faster than 10 kph, but when disturbed they can attain speeds of 30 kph. Their voices are quite loud and can be heard many kilometers away with underwater listening devices. Each whale also emits a stereotyped, repetitive sequence of or more clicks when it meets another whale. The diving behavior of a medium-sized female sperm whale off the Kumano Coast, Japan, was studied using a suction-cup-attached TDR time depth recorder tag. In contrast to the smooth skin of most large whales, its back skin is usually wrinkly and has been likened to a prune by whale-watching enthusiasts. The ribs are bound to the spine by flexible cartilage, which allows the ribcage to collapse rather than snap under high pressure. Bones show the same pitting that signals decompression sickness in humans. Older skeletons showed the most extensive pitting, whereas calves showed no damage. This damage may indicate that sperm whales are susceptible to decompression sickness, and sudden surfacing could be lethal to them. Like that of all cetaceans, the spine of the sperm whale has reduced zygapophysial joints , of which the remnants are modified and are positioned higher on the vertebral dorsal spinous process, hugging it laterally, to prevent extensive lateral bending and facilitate more dorso-ventral bending. These evolutionary modifications make the spine more flexible but weaker than the spines of terrestrial vertebrates. Like that of other toothed whales , the skull of the sperm whale is asymmetrical so as to aid echolocation. Sound waves that strike the whale from different directions will not be channeled in the same way. The sperm whale's lower jaw is very narrow and underslung. One hypothesis is that the teeth are used in aggression between males. Rudimentary teeth are also present in the upper jaw, but these rarely emerge into the mouth. Like the age-rings in a tree, the teeth build distinct layers of cementum and dentine as they grow. The brain is the largest known of any modern or extinct animal, weighing on average about 7. Elephants and dolphins also have larger brains than humans. The sperm whale's cerebrum is the largest in all mammalia, both in absolute and relative terms. The olfactory system is reduced, suggesting that the sperm whale has a poor sense of taste and smell. By contrast, the auditory system is enlarged. The pyramidal tract is poorly developed, reflecting the reduction of its limbs. The sperm whale respiratory system has adapted to cope with drastic pressure changes when diving. The flexible ribcage allows lung collapse, reducing nitrogen intake, and metabolism can decrease to conserve oxygen. Sperm whales spout breathe 3—5 times per minute at rest, increasing to 6—7 times per minute after a dive. The blow is a noisy, single stream that rises up to 2 metres 6. The sperm whale has the longest intestinal system in the world, [65] exceeding m in larger specimens. The first secretes no gastric juices and has very thick muscular walls to crush the food since whales cannot chew and resist the claw and sucker attacks of swallowed squid. The second chamber is larger and is where digestion takes place. Undigested squid beaks accumulate in the second chamber — as many as 18, have been found in some dissected specimens. Such beaks precipitate the formation of ambergris. The diameter of the aortic arch increases as it leaves the heart. This bulbous expansion acts as a windkessel , ensuring a steady blood flow as the heart rate slows during diving. There is no costocervical artery. There is no direct connection between the internal carotid artery and the vessels of the brain. The oxygenated blood can be directed towards only the brain and other essential organs when oxygen levels deplete. The complex arterial retia mirabilia of the sperm whale are more extensive and larger than those of any other cetacean. Atop the whale's skull is positioned a large complex of organs filled with a liquid mixture of fats and waxes called spermaceti. The purpose of this complex is to generate powerful and focused clicking sounds, which the sperm whale uses for echolocation and communication. The spermaceti organ is like a large barrel of spermaceti. Its surrounding wall, known as the case , is extremely tough and fibrous. The case can hold within it up to 1, litres of spermaceti. The proportion of wax esters in the spermaceti organ increases with the age of the whale: Below the spermaceti organ lies the "junk" which consists of compartments of spermaceti separated by cartilage. It is analogous to the melon found in other toothed whales. Running through the head are two air passages. The left passage runs alongside the spermaceti organ and goes directly to the blowhole, whilst the right passage runs underneath the spermaceti organ and passes air through a pair of phonic lips and into the distal sac at the very front of the nose. The distal sac is connected to the blowhole and the terminus of the left passage. When the whale is submerged, it can close the blowhole, and air that passes through the phonic lips can circulate back to the lungs. The sperm whale, unlike other odontocetes, has only one pair of phonic lips, whereas all other toothed whales have two, [97] and it is located at the front of the nose instead of behind the melon. At the posterior end of this spermaceti complex is the frontal sac, which covers the concave surface of the cranium. The anterior wall is smooth. The knobbly surface reflects sound waves that come through the spermaceti organ from the phonic lips. The grooves between the knobs trap a film of air that is consistent whatever the orientation or depth of the whale, making it an excellent sound mirror. The spermaceti organs may also help adjust the whale's buoyancy. It is hypothesized that before the whale dives, cold water enters the organ, and it is likely that the blood vessels constrict, reducing blood flow, and, hence, temperature. The wax therefore solidifies and reduces in volume. Herman Melville 's fictional story Moby Dick suggests that the "case" containing the spermaceti serves as a battering ram for use in fights between males. A piece of the posterior wall of the frontal sac. The grooves between the knobs trap a consistent film of air, making it an excellent sound mirror. The sperm whale's eye does not differ greatly from those of other toothed whales except in size. The cornea is elliptical and the lens is spherical. There are no ciliary muscles. The choroid is very thick and contains a fibrous tapetum lucidum. Like other toothed whales, the sperm whale can retract and protrude its eyes thanks to a 2-cm-thick retractor muscle attached around the eye at the equator, [] but are unable to roll the eyes in their sockets. According to Fristrup and Harbison , [] sperm whales eyes afford good vision and sensitivity to light. They conjectured that sperm whales use vision to hunt squid, either by detecting silhouettes from below or by detecting bioluminescence. If sperm whales detect silhouettes, Fristrup and Harbison suggested that they hunt upside down, allowing them to use the forward parts of the ventral visual fields for binocular vision. For some time researchers have been aware that pods of sperm whales may sleep for short periods, assuming a vertical position with their heads just below or at the surface. A study published in Current Biology recorded evidence that whales may sleep with both sides of the brain. It appears that some whales may fall into a deep sleep for about 7 percent of the time, most often between 6 p. When echolocating , the sperm whale emits a directionally focused beam of broadband clicks. Clicks are generated by forcing air through a pair of phonic lips also known as "monkey lips" or "museau de singe" at the front end of the nose, just below the blowhole. The sound then travels backwards along the length of the nose through the spermaceti organ. Most of the sound energy is then reflected off the frontal sac at the cranium and into the melon, whose lens-like structure focuses it. This back and forth reflection which happens on the scale of a few milliseconds creates a multi-pulse click structure. However, if the whale matures and the size of the spermaceti organ increases, the tone of the whale's click will also change. A continuous fat-filled canal transmits received sounds to the inner ear. The source of the air forced through the phonic lips is the right nasal passage. While the left nasal passage opens to the blow hole, the right nasal passage has evolved to supply air to the phonic lips. It is thought that the nostrils of the land-based ancestor of the sperm whale migrated through evolution to their current functions, the left nostril becoming the blowhole and the right nostril becoming the phonic lips. Air that passes through the phonic lips passes into the distal sac, then back down through the left nasal passage. This recycling of air allows the whale to continuously generate clicks for as long as it is submerged. A creak is a rapid series of high-frequency clicks that sounds somewhat like a creaky door hinge. It is typically used when homing in on prey. A coda is a short pattern of 3 to 20 clicks that is used in social situations. They were once thought to be a way by which individuals identified themselves, but individuals have been observed producing multiple codas, and the same codas are used by multiple individuals. Despite evidence that sperm whales share similar codas, it is still unknown whether sperm whales possess individually specific coda repertoires or whether individuals make codas at different rates. Slow clicks are heard only in the presence of males it is not certain whether females occasionally make them. Outside breeding grounds, slow clicks are rarely heard, and usually near the surface. Sperm whales are among the most cosmopolitan species. They are relatively abundant from the poles to the equator and are found in all the oceans. Populations are denser close to continental shelves and canyons. Historical catch records suggest there could have been smaller aggression grounds in the Sea of Japan as well. Grown males are known to enter surprisingly shallow bays to rest whales will be in state of rest during these occasions. There are unique, coastal groups reported from various areas among the globe such as Scotland , [] Shiretoko Peninsula, off Kaikoura, in Davao Gulf. Such coastal groups were more abundant in pre-whaling days. Genetic analysis indicates that the world population of sperm whales originated in the Pacific Ocean from a population of about 10, animals around , years ago when expanding ice caps blocked off their access to other seas. In particular, colonization of the Atlantic was revealed to have occurred multiple times during this expansion of their range. One study published in collected evidence that suggests that female sperm whales may collaborate when hunting Humboldt squid. It is suggested that the whales can see the squid silhouetted above them against the dim surface light. An older study, examining whales captured by the New Zealand whaling fleet in the Cook Strait region, found a 1. Long-line fishing operations in the Gulf of Alaska complain that sperm whales take advantage of their fishing operations to eat desirable species straight off the line, sparing the whales the need to hunt. Video footage has been captured of a large male sperm whale "bouncing" a long line, to gain the fish. The sharp beak of a consumed squid lodged in the whale's intestine may lead to the production of ambergris , analogous to the production of pearls. Sperm whales hunt through echolocation. Their clicks are among the most powerful sounds in the animal kingdom see above. It has been hypothesised that it can stun prey with its clicks. Home Highlights Sperm Whale.

All rights reserved. Sperm whales' heads are filled with a mysterious substance called spermaceti. Scientists have yet to understand its function, but believe it may help the animal regulate its buoyancy. They have the largest brain of any creature known to have lived on Earth. Their heads also hold large quantities of a substance called spermaceti..

Loose family groups Sperm whale life span about 30 individuals, however, are more common. Older males are usually solitary except Sperm whale life span the breeding Sperm whale life span. During the breeding season, breeding schools composed of large males and Sperm whale life span mixed group of females and males of various ages form. At this point, there is intense competition among the males for females including physical competition resulting in battle scars all over the heads of males.

Females mature sexually at years, and males mature at approximately 10 years, although males do not mate until years old because read more usually do not have a high enough social status in a breeding school until that point. Maximum known life span is 77 years. Gestation period is months and a single calf is born, which nurses for up to 2 years. The reproductive cycle occurs in females every years.

About the Sperm Whale Sperm whales are easily recognized by their massive heads and prominent rounded foreheads. These toothed whales eat thousands of pounds of fish and squid—about one ton per day. Despite Sperm whale life span population drops due to whaling, sperm whales are still fairly numerous.

Maximum known life span is 77 years. Gestation period is months and a single calf is born, which nurses for up to 2 years. The reproductive cycle occurs in females every years. The peak of the mating season is in the spring in both northern and southern hemispheres so that most calves are born in the fall. Being fiercely aggressive when attacked, bull sperm whales posed a threat to small-boat whalers in the 19th century. Sperm whales were no match for modern whaling equipment, however. Sperm whales were once abundant in the Gulf of Mexico, but due to commercial whaling operations, they are seldom seen in that area now. Worldwide sperm whale populations are more stable than that of many other whales. The sperm whale is now the most abundant of the great whales because it has been hunted with less intensity than the baleen whales. Worldwide, sperm whales number about 1,, A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable see Section V , and it is therefore considered to be facing a high risk of extinction in the wild.

Their dorsal fin is replaced by a hump and by a series of longitudinal ridges on the posterior part of their backs, and their pectoral fins are quite small, approximately 2 m long.

Their clicks are among the most powerful sounds in the animal kingdom see above. It has been hypothesised that it can stun prey with its clicks. Experimental studies attempting to duplicate this effect have been unable to replicate the supposed injuries, casting doubt on this idea. It has been stated that sperm whales, as well as other large cetaceans, help fertilise the surface of the ocean by consuming nutrients in the depths and transporting those nutrients to the oceans' surface when they defecate, an effect known as the whale pump. Sperm whales can live 70 years or more. How they choose mates has not been definitively determined. Males will fight with each other over females, and males will mate with multiple females, making them polygynous , but they do not dominate the group as in a harem. Females become fertile at around 9 years of age. The other adults may jostle and bite the newborn in its first hours. Lactation proceeds for 19 to 42 months, but calves, rarely, may suckle up to 13 years. This gives it a consistency similar to cottage cheese, [] which prevents it from dissolving in the water before the calf can eat it. Males become sexually mature at 18 years. Upon reaching sexual maturity, males move to higher latitudes , where the water is colder and feeding is more productive. Females remain at lower latitudes. Adult males who are not breeding live solitary lives, whereas females and juvenile males live together in groups. The main driving force for the sexual segregation of adult sperm whales is scramble competition for mesopelagic squid. Mature males sometimes form loose bachelor groups with other males of similar age and size. A social unit is a group of sperm whales who live and travel together over a period of years. Individuals rarely, if ever, join or leave a social unit. There is a huge variance in the size of social units. They are most commonly between six and nine individuals in size but can have more than twenty. Socializing usually takes place in the afternoon. When sperm whales socialize, they emit complex patterns of clicks called codas. The teeth however do not appear to be necessary for biting or consuming prey as sperm whales that do not possess teeth appear to be able to consume their prey with little or no issues when compared to toothed sperm whales. In terms of color sperm whales are usually dark gray color, but can occasionally be a light grey or black coloring as well. To assist with swimming sperm whales have a small paddle shaped fins used for steering int eh water and large flukes to propel themselves forward. The sperm whale is known to have the largest brain of any known animal currently in existence. Depredation sometimes results in injury or entanglement. Underwater noise pollution can interrupt the normal behavior of sperm whales, which rely on sound to communicate. As ocean noise increases from human sources, communication space decreases—the whales cannot hear each other, or discern other signals in their environment as they used to in an undisturbed ocean. Different levels of sound can disturb important activities, such as feeding, migrating, and socializing. Mounting evidence from scientific research has documented that ocean noise also causes marine mammals to change the frequency or amplitude of calls, decrease foraging behavior, become displaced from preferred habitat, or increase the level of stress hormones in their bodies. If loud enough, noise can cause permanent or temporary hearing loss. Sperm whales can ingest marine debris, as do many marine animals. Debris in the deep scattering layer where sperm whales feed could be mistaken for prey and incidentally ingested, leading to possible injury or death. The effects of climate and oceanographic change on sperm whales are uncertain, but both can potentially greatly affect habitat and food availability. Site selection for whale migration, feeding, and breeding for sperm whales may be influenced by factors such as ocean currents and water temperature. Increases in global temperatures are expected to have profound impacts on arctic and subarctic ecosystems, and these impacts are projected to accelerate during this century. However, the feeding range of sperm whales is likely the greatest of any species on earth, and, consequently, sperm whales are likely to be more resilient to climate change than species with narrower habitat preferences. The threat of contaminants and pollutants to sperm whales and their habitat is highly uncertain and further study is necessary to assess the impacts of this threat. Little is known about the possible long-term and transgenerational effects of exposure to pollutants. Marine mammals are considered to be good indicators for concentrations of metal and pollutant accumulation in the environment due to their long lifespan and in some cases position near the top of marine food webs. NOAA Fisheries is committed to the protection and recovery of sperm whales. Targeted management actions taken to protect these whales include:. Our research projects have discovered new aspects of sperm whale biology, behavior, and ecology and helped us better understand the challenges that sperm whales face. This research is especially important in rebuilding endangered populations. Our work includes, but is not limited to:. Be responsible when viewing marine life in the wild.

However, sperm whale ivory contains a much thicker inner layer. Though a widely practised art in the nineteenth century, scrimshaw using genuine sperm whale ivory declined substantially after the retirement of the whaling fleets in the s. Modern whaling was more efficient than open-boat whaling, employing steam-powered ships and exploding harpoons. Initially, modern whaling activity focused on large baleen whales , but as these populations were taken, sperm whaling increased. Spermaceti , the fine waxy oil produced by sperm whales, was in high demand. In both the to and to seasons, Norwegian expeditions took over 3, sperm whales off the coast of Peru alone. After World War II , whaling continued unabated to obtain oil for cosmetics and high-performance machinery, such as automobile transmissions. The hunting led to the near extinction of large whales, including sperm whales, until bans on whale oil use were instituted in The International Whaling Commission gave the species full protection in but hunting by Japan in the northern Pacific Ocean continued until It is estimated that the historic worldwide population numbered 1,, before commercial sperm whaling began in the early eighteenth century. Sperm whales increase levels of primary production and carbon export by depositing iron-rich faeces into surface waters of the Southern Ocean. The iron-rich faeces cause phytoplankton to grow and take up more carbon from the atmosphere. When the phytoplankton dies, it sinks to the deep ocean and takes the atmospheric carbon with it. By reducing the abundance of sperm whales in the Southern Ocean, whaling has resulted in an extra 2 million tonnes of carbon remaining in the atmosphere each year. Remaining sperm whale populations are large enough that the species' conservation status is rated as vulnerable rather than endangered. The total number of sperm whales in the world is unknown, but is thought to be in the hundreds of thousands. Commercial whaling has ceased, [3] and the species is protected almost worldwide, though records indicate that in the eleven-year period starting from , Japan has caught 51 sperm whales. Fishermen do not target the creatures sperm whales eat, [3] but long-line fishing operations in the Gulf of Alaska have complained about sperm whales stealing fish from their lines. Currently, entanglement in fishing nets and collisions with ships represent the greatest threats to the sperm whale population. It is listed on Appendix I [] as this species has been categorized as being in danger of extinction throughout all or a significant proportion of their range and CMS Parties strive towards strictly protecting these animals, conserving or restoring the places where they live, mitigating obstacles to migration and controlling other factors that might endanger them. It is listed on Appendix II [] as it has an unfavourable conservation status or would benefit significantly from international co-operation organised by tailored agreements. Rope-mounted teeth are important cultural objects throughout the Pacific. In Fiji the teeth are known as tabua , traditionally given as gifts for atonement or esteem called sevusevu , and were important in negotiations between rival chiefs. They occurred often in necklaces. The teeth were originally rare in Fiji and Tonga , which exported teeth, but with the Europeans' arrival, teeth flooded the market and this "currency" collapsed. The oversupply led in turn to the development of the European art of scrimshaw. Herman Melville 's novel Moby-Dick is based on a true story about a sperm whale that attacked and sank the whaleship Essex. In Jules Verne 's Twenty Thousand Leagues Under the Sea , the Nautilus fights a group of "cachalots" sperm whales to protect a pod Southern right whales from their attacks. Verne portrays them as being savage hunters "nothing but mouth and teeth. Sperm whales are not the easiest of whales to watch , due to their long dive times and ability to travel long distances underwater. However, due to the distinctive look and large size of the whale, watching is increasingly popular.

One common theory is that the fluid—which hardens to wax when cold—helps the whale alter its buoyancy so it can dive deep and rise again. Sperm whales are known to dive as deep as 3, feet in search of squid to eat. These giant mammals must hold their breath for up to 90 minutes on such dives. Sperm whales are often spotted in groups called pods of some 15 to 20 animals. Female whales typically reach sexually maturity between the ages of 7 — 14 while males usually reach sexual maturity after the age of In terms of natural threats sperm whales are known to face occasional attacks from killer whales. In the past the sperm whale was a victim of commercial whaling, however they are now considered a protected species and have recovered some of their losses over the years. We use cookies to ensure that we give you the best experience on our website. Sperm whales were a prime target of the commercial whaling industry from to Whaling greatly reduced the sperm whale population. Whaling is no longer a major threat and its population is still recovering. NOAA Fisheries and our partners are dedicated to conserving and rebuilding the sperm whale population. We use a variety of innovative techniques to study, protect, and rescue these endangered whales. We engage our partners as we develop regulations and management plans that encourage recovery, foster healthy fisheries, reduce the risk of entanglements, create whale-safe shipping practices, and reduce ocean noise. The International Whaling Commission placed a moratorium on commercial whaling in The species is still recovering, and its numbers are likely increasing. Currently, there is no exact accounting of the total number of sperm whales worldwide. The best estimate of worldwide sperm whale population is between , and , individuals. Sperm whales are the only living cetacean that has a single blowhole asymmetrically situated on the left side of the crown of the head. Their heads are extremely large, accounting for about one-third of total body length. The skin just behind the head is often wrinkled. Their lower jaw is narrow and the portion of the jaw closest to the teeth is white. The interior of the mouth is often bright white as well. There are between 20 and 26 large teeth in each side of the lower jaw. The teeth in the upper jaw rarely break through the gums. Sperm whale flippers are paddle-shaped and small compared to the size of the body, and their flukes are triangular. They have small dorsal fins that are low, thick, and usually rounded. Sperm whales hunt for food during deep dives that routinely reach depths of 2, feet and can last for 45 minutes. They are capable of diving to depths of over 10, feet for over 60 minutes. After long, deep dives, individuals come to the surface to breathe and recover for approximately nine minutes. Because sperm whales spend most of their time in deep waters, their diet consists of many larger species that also occupy deep ocean waters. This includes squid, sharks, skates, and fish. Sperm whales can consume about 3 to 3. The lower teeth fit into sockets in the upper jaw. The gullet of Physeter macrocephalus is the largest among cetaceans; it is in fact the only gullet large enough to swallow a human. Their dorsal fin is replaced by a hump and by a series of longitudinal ridges on the posterior part of their backs, and their pectoral fins are quite small, approximately 2 m long. Tail flukes are 4- 4. The blubber layer of sperm whales is quite thick, up to 35 cm. With respect to coloration, males often become paler and are sometimes piebald with age. Both sexes have white in the genital and anal regions and on the lower jaws. The mass of mature sperm whales ranges between 35, 57, kg. Sperm whales are very deep divers and may stay submerged from 20 minutes to over an hour..

Vocal communication may involve a series Sperm whale life span clicking sounds that are extremely loud and can be heard over great distances. NOAA Fisheries is working to minimize effects from human activities that are detrimental to the recovery of sperm whale populations in the U.

Mounting Sperm whale life span suggests that exposure to intense underwater sound may cause injury to sperm whales resulting in loss of hearing, or possibly stranding and ultimately death. NOAA Fisheries is investigating sound production and hearing in marine animals, as well as the effects of sound on whale behavior.

We work with volunteer networks in coastal states to respond to marine mammal strandings. When Sperm whale life span animals are found dead, our scientists work to understand and investigate the cause of death. NOAA Fisheries also responds to marine mammals entangled in fishing gear or other lines or debris and, when feasible, attempts disentanglement.

Both sexes have white in the genital and anal regions and on the lower jaws. The mass of mature sperm whales ranges between 35, 57, kg. Sperm whales are very deep divers and may stay submerged from 20 minutes to over an hour. When they surface, sperm whales typically blow times before descending again. They produce a visible spout made by the condensation of the moisture combined with a mucous foam from the sinuses. Sperm whales typically swim at speeds no faster than 10 kph, but when disturbed they can attain speeds of 30 kph. Their voices are quite loud and can be heard many kilometers away with underwater listening devices. Each whale also emits a stereotyped, repetitive sequence of or more clicks when it meets another whale. The diving behavior of a medium-sized female sperm whale off the Kumano Coast, Japan, was studied using a suction-cup-attached TDR time depth recorder tag. Undigested squid beaks accumulate in the second chamber — as many as 18, have been found in some dissected specimens. Such beaks precipitate the formation of ambergris. The diameter of the aortic arch increases as it leaves the heart. This bulbous expansion acts as a windkessel , ensuring a steady blood flow as the heart rate slows during diving. There is no costocervical artery. There is no direct connection between the internal carotid artery and the vessels of the brain. The oxygenated blood can be directed towards only the brain and other essential organs when oxygen levels deplete. The complex arterial retia mirabilia of the sperm whale are more extensive and larger than those of any other cetacean. Atop the whale's skull is positioned a large complex of organs filled with a liquid mixture of fats and waxes called spermaceti. The purpose of this complex is to generate powerful and focused clicking sounds, which the sperm whale uses for echolocation and communication. The spermaceti organ is like a large barrel of spermaceti. Its surrounding wall, known as the case , is extremely tough and fibrous. The case can hold within it up to 1, litres of spermaceti. The proportion of wax esters in the spermaceti organ increases with the age of the whale: Below the spermaceti organ lies the "junk" which consists of compartments of spermaceti separated by cartilage. It is analogous to the melon found in other toothed whales. Running through the head are two air passages. The left passage runs alongside the spermaceti organ and goes directly to the blowhole, whilst the right passage runs underneath the spermaceti organ and passes air through a pair of phonic lips and into the distal sac at the very front of the nose. The distal sac is connected to the blowhole and the terminus of the left passage. When the whale is submerged, it can close the blowhole, and air that passes through the phonic lips can circulate back to the lungs. The sperm whale, unlike other odontocetes, has only one pair of phonic lips, whereas all other toothed whales have two, [97] and it is located at the front of the nose instead of behind the melon. At the posterior end of this spermaceti complex is the frontal sac, which covers the concave surface of the cranium. The anterior wall is smooth. The knobbly surface reflects sound waves that come through the spermaceti organ from the phonic lips. The grooves between the knobs trap a film of air that is consistent whatever the orientation or depth of the whale, making it an excellent sound mirror. The spermaceti organs may also help adjust the whale's buoyancy. It is hypothesized that before the whale dives, cold water enters the organ, and it is likely that the blood vessels constrict, reducing blood flow, and, hence, temperature. The wax therefore solidifies and reduces in volume. Herman Melville 's fictional story Moby Dick suggests that the "case" containing the spermaceti serves as a battering ram for use in fights between males. A piece of the posterior wall of the frontal sac. The grooves between the knobs trap a consistent film of air, making it an excellent sound mirror. The sperm whale's eye does not differ greatly from those of other toothed whales except in size. The cornea is elliptical and the lens is spherical. There are no ciliary muscles. The choroid is very thick and contains a fibrous tapetum lucidum. Like other toothed whales, the sperm whale can retract and protrude its eyes thanks to a 2-cm-thick retractor muscle attached around the eye at the equator, [] but are unable to roll the eyes in their sockets. According to Fristrup and Harbison , [] sperm whales eyes afford good vision and sensitivity to light. They conjectured that sperm whales use vision to hunt squid, either by detecting silhouettes from below or by detecting bioluminescence. If sperm whales detect silhouettes, Fristrup and Harbison suggested that they hunt upside down, allowing them to use the forward parts of the ventral visual fields for binocular vision. For some time researchers have been aware that pods of sperm whales may sleep for short periods, assuming a vertical position with their heads just below or at the surface. A study published in Current Biology recorded evidence that whales may sleep with both sides of the brain. It appears that some whales may fall into a deep sleep for about 7 percent of the time, most often between 6 p. When echolocating , the sperm whale emits a directionally focused beam of broadband clicks. Clicks are generated by forcing air through a pair of phonic lips also known as "monkey lips" or "museau de singe" at the front end of the nose, just below the blowhole. The sound then travels backwards along the length of the nose through the spermaceti organ. Most of the sound energy is then reflected off the frontal sac at the cranium and into the melon, whose lens-like structure focuses it. This back and forth reflection which happens on the scale of a few milliseconds creates a multi-pulse click structure. However, if the whale matures and the size of the spermaceti organ increases, the tone of the whale's click will also change. A continuous fat-filled canal transmits received sounds to the inner ear. The source of the air forced through the phonic lips is the right nasal passage. While the left nasal passage opens to the blow hole, the right nasal passage has evolved to supply air to the phonic lips. It is thought that the nostrils of the land-based ancestor of the sperm whale migrated through evolution to their current functions, the left nostril becoming the blowhole and the right nostril becoming the phonic lips. Air that passes through the phonic lips passes into the distal sac, then back down through the left nasal passage. This recycling of air allows the whale to continuously generate clicks for as long as it is submerged. A creak is a rapid series of high-frequency clicks that sounds somewhat like a creaky door hinge. It is typically used when homing in on prey. A coda is a short pattern of 3 to 20 clicks that is used in social situations. They were once thought to be a way by which individuals identified themselves, but individuals have been observed producing multiple codas, and the same codas are used by multiple individuals. Despite evidence that sperm whales share similar codas, it is still unknown whether sperm whales possess individually specific coda repertoires or whether individuals make codas at different rates. Slow clicks are heard only in the presence of males it is not certain whether females occasionally make them. Outside breeding grounds, slow clicks are rarely heard, and usually near the surface. Sperm whales are among the most cosmopolitan species. They are relatively abundant from the poles to the equator and are found in all the oceans. Populations are denser close to continental shelves and canyons. Historical catch records suggest there could have been smaller aggression grounds in the Sea of Japan as well. Grown males are known to enter surprisingly shallow bays to rest whales will be in state of rest during these occasions. There are unique, coastal groups reported from various areas among the globe such as Scotland , [] Shiretoko Peninsula, off Kaikoura, in Davao Gulf. Such coastal groups were more abundant in pre-whaling days. Genetic analysis indicates that the world population of sperm whales originated in the Pacific Ocean from a population of about 10, animals around , years ago when expanding ice caps blocked off their access to other seas. In particular, colonization of the Atlantic was revealed to have occurred multiple times during this expansion of their range. One study published in collected evidence that suggests that female sperm whales may collaborate when hunting Humboldt squid. It is suggested that the whales can see the squid silhouetted above them against the dim surface light. An older study, examining whales captured by the New Zealand whaling fleet in the Cook Strait region, found a 1. Long-line fishing operations in the Gulf of Alaska complain that sperm whales take advantage of their fishing operations to eat desirable species straight off the line, sparing the whales the need to hunt. Video footage has been captured of a large male sperm whale "bouncing" a long line, to gain the fish. The sharp beak of a consumed squid lodged in the whale's intestine may lead to the production of ambergris , analogous to the production of pearls. Sperm whales hunt through echolocation. Their clicks are among the most powerful sounds in the animal kingdom see above. It has been hypothesised that it can stun prey with its clicks. Experimental studies attempting to duplicate this effect have been unable to replicate the supposed injuries, casting doubt on this idea. It has been stated that sperm whales, as well as other large cetaceans, help fertilise the surface of the ocean by consuming nutrients in the depths and transporting those nutrients to the oceans' surface when they defecate, an effect known as the whale pump. Sperm whales can live 70 years or more. How they choose mates has not been definitively determined. Males will fight with each other over females, and males will mate with multiple females, making them polygynous , but they do not dominate the group as in a harem. Females become fertile at around 9 years of age. The other adults may jostle and bite the newborn in its first hours. Lactation proceeds for 19 to 42 months, but calves, rarely, may suckle up to 13 years. This gives it a consistency similar to cottage cheese, [] which prevents it from dissolving in the water before the calf can eat it. Males become sexually mature at 18 years. Upon reaching sexual maturity, males move to higher latitudes , where the water is colder and feeding is more productive. Females remain at lower latitudes. Adult males who are not breeding live solitary lives, whereas females and juvenile males live together in groups. The main driving force for the sexual segregation of adult sperm whales is scramble competition for mesopelagic squid. Mature males sometimes form loose bachelor groups with other males of similar age and size. A social unit is a group of sperm whales who live and travel together over a period of years. Individuals rarely, if ever, join or leave a social unit. There is a huge variance in the size of social units. They are most commonly between six and nine individuals in size but can have more than twenty. Socializing usually takes place in the afternoon. When sperm whales socialize, they emit complex patterns of clicks called codas. They will spend much of the time rubbing against each other. Tracking of diving whales suggests that groups engage in herding of prey, similar to bait balls created by other species, though the research needs to be confirmed by tracking the prey. The most common natural predator of sperm whales is the orca , but pilot whales and false killer whales sometimes harass them. The adults will protect their calves or an injured adult by encircling them. They may face inwards with their tails out the 'marguerite formation', named after the flower. The sperm whale is known to have the largest brain of any known animal currently in existence. A standard diet for sperm whales usually consists of medium to large squid , octopus and fish , however large squid appear to be the most commonly hunted marine animal in their diet. Because the sperm whale hunts for food well below the surface of the water sperm whales use echolocation to hunt for food and navigate the ocean. One study found 3 sperm whales appearing to be attacking a megamouth shark when looking for food. Sperm whales are known to have 20 — 26 teeth on each side of their lower jaw with the teeth on the upper jaw rarely breaking through the surface. Their heads also hold large quantities of a substance called spermaceti. Whalers once believed that the oily fluid was sperm, but scientists still do not understand the function of spermaceti. One common theory is that the fluid—which hardens to wax when cold—helps the whale alter its buoyancy so it can dive deep and rise again. Sperm whales are known to dive as deep as 3, feet in search of squid to eat. These giant mammals must hold their breath for up to 90 minutes on such dives. These data shed light on the evolution of sociality at sea and the nature of social bonds in groups of free-ranging whales.
