This bulbous expansion acts as a windkessel, ensuring a steady blood flow as the heart rate slows during diving. [228] By the following decade, the French had entered the trade, also employing American expertise. Despite the public’s passing familiarity with sperm whales, many people have wondered why they are so named. [208] However, more recent studies, based on various combinations of comparative anatomy and molecular phylogenetics, criticised Milinkovitch's analysis on technical grounds and reaffirmed that the Odontoceti are monophyletic. Males make a lot of slow clicks in breeding grounds (74% of the time), both near the surface and at depth, which suggests they are primarily mating signals. They are easily recognized by their enormous square head and narrow lower jaw. Origins of the Names of Ireland's Sperm Whales & That of the Greatest Literary Incarnation of Their Species, Moby Dick And modern biologists assume that it probably functions to help with buoyancy or aid in echolocation 3. (1907) this is even implicit in the name itself for ‘amber’ comes from the Arabic ‘anbar’ which also means the sperm whale in Arabic. Honorific names for whales or families of whales are Tūtarakauika, te Kauika Tangaroa, Wehengakāuki, Ruamano, Taniwha, and Tū-te-raki-hau-noa. Evolutionary family tree of sperm whales. Spermaceti was used chiefly in ointments, cosmetic creams, fine wax candles, pomades, and textile finishing; later it was used for industrial lubricants. These substances found a variety of commercial applications, such as candles, soap, cosmetics, machine oil, other specialised lubricants, lamp oil, pencils, crayons, leather waterproofing, rust-proofing materials and many pharmaceutical compounds. [140], Populations are denser close to continental shelves and canyons. [155] Such dives can last more than an hour. It is typically used when homing in on prey. [126], Air that passes through the phonic lips passes into the distal sac, then back down through the left nasal passage. [10] Among several regions, such as along coastal waters of southern Australia, sperm whales have been considered to be locally extinct. Popular locations for sperm whale watching include the town of Kaikoura on New Zealand's South Island, Andenes and Tromsø in Arctic Norway; as well as the Azores, where the continental shelf is so narrow that whales can be observed from the shore,[141][250] and Dominica[251] where a long-term scientific research program, The Dominica Sperm Whale Project, has been in operation since 2005. The sperm whale is also known as the "cachalot", which is thought to derive from the archaic French for "tooth" or "big teeth", as preserved for example in caishau in the Gascon dialect (a word of either Romance or Basque origin). [6][7] The sperm whale uses echolocation and vocalization as loud as 230 decibels (re 1 µPa m) underwater. It doesn’t have to be a conventional or direct path, just one that works for you. [84] More typical dives are around 400 metres (1,310 ft) and 35 minutes in duration. In most modern publications the sperm whale is classified as the sole species, Physeter macrocephalus, in the family Physeteridae (and thus the only species in its genus). Sperm whales are listed on Appendix I[240] and Appendix II[240] of the Convention on the Conservation of Migratory Species of Wild Animals (CMS). Certainly the association dates from the earliest reference to ambergris known to me, that of the ninth century Arab traveller. Experimental studies attempting to duplicate this effect have been unable to replicate the supposed injuries, casting doubt on this idea. [3] From that date until 1946, the population appears to have partially recovered as whaling activity decreased, but after the Second World War, the population declined even further, to 33 per cent of the pre-whaling population. There is no direct connection between the internal carotid artery and the vessels of the brain. [9], Males become sexually mature at 18 years. [40] The whales rarely, if ever, leave their group. [40] It has a series of ridges on the back's caudal third instead of a dorsal fin. The complex arterial retia mirabilia of the sperm whale are more extensive and larger than those of any other cetacean. [193] However, formations in non-dangerous situations have been recorded as well. [182] It has an energy content of roughly 3,840 kcal/kg,[180] compared to just 640 kcal/kg in cow milk. Spermaceti oil was important in public lighting (for example, in lighthouses, where it was used in the United States until 1862, when it was replaced by lard oil, in turn replaced by petroleum) and for lubricating the machines (such as those used in cotton mills) of the Industrial Revolution. Two species of the related extant genus Kogia, the pygmy sperm whale Kogia breviceps and the dwarf sperm whale K. sima, are placed either in this family or in the family Kogiidae. 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. [127], A creak is a rapid series of high-frequency clicks that sounds somewhat like a creaky door hinge. [40] Odontoceti (toothed whales) breathe air at the surface through a single, S-shaped blowhole, which is extremely skewed to the left. In this instance, it led to the choice of P. macrocephalus over P. catodon, a view re-stated in Holthuis, 1987. [153], Genetic analysis indicates that the world population of sperm whales originated in the Pacific Ocean from a population of about 10,000 animals around 100,000 years ago, when expanding ice caps blocked off their access to other seas. Sperm whales can live 70 years or more.[9][10][11]. [40] Myoglobin, which stores oxygen in muscle tissue, is much more abundant than in terrestrial animals. Each of these teeth, up to 20 cm (8 in) and 8 cm (3 in) across, are hollow for the first half of their length. Diaphorocetus, from Argentina, has been dated to the early Miocene. 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. [103] The spermaceti at the core of the organ has a higher wax content than the outer areas. The sperm whale is also known as the "cachalot", which is thought to derive from the archaic French for "tooth" or "big teeth", as preserved for example in caishau in the Gascon dialect (a word of either Romance[14] or Basque[15] origin). [56] Within the basin of the cranium, the openings of the bony narial tubes (from which the nasal passages spring) are skewed towards the left side of the skull. [246][247] The fearsome reputation perpetuated by Melville was based on bull whales' ability to fiercely defend themselves from attacks by early whalers, smashing whaling boats and, occasionally, attacking and destroying whaling ships. [112], 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. [9][38][36][42][43][44], There are old reports of sperm whales approaching, reaching or exceeding 80 feet (24 m) in length but there is disagreement as to the accuracy of these claims which are often considered exaggerations or as being measured along the curves of the body. Purves, M. G., Agnew, D. J., Balguerias, E., Moreno, C. A., & Watkins, B. In particular, colonization of the Atlantic was revealed to have occurred multiple times during this expansion of their range. It is a member of the unranked clade Cetacea, with all the whales, dolphins, and porpoises, and further classified into Odontoceti, containing all the toothed whales and dolphins. Times News. Initially, modern whaling activity focused on large baleen whales, but as these populations were taken, sperm whaling increased. [90] Geographically separate pods exhibit distinct dialects. The sperm whale family is sometimes treated as a superfamily, Physeteroidea (M… Currently the Endangered Species Act and the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), prevents the sales of or trade in sperm whale ivory harvested after 1973 or scrimshaw crafted from it. [9] Coastal areas with significant sperm whale populations include the Azores and Dominica. [10][51][52], The ribs are bound to the spine by flexible cartilage, which allows the ribcage to collapse rather than snap under high pressure. The first ever sighting in Pakistan was made in 2017. From 1770 to 1775 Massachusetts, New York, Connecticut, and Rhode Island ports produced 45,000 barrels of sperm oil annually, compared to 8,500 of whale oil. Learn more. Whalers valued spermaceti (the name of the material within the spermaceti organ) because it could be cooled into a wax that could be made into ointments, cosmetic creams, fine wax candles, pomades, textile finishing products, and industrial lubricants. The name sperm whale is a truncated form of spermaceti whale. Use * for blank tiles (max 2) Advanced Search Advanced Search: Use * for blank spaces Advanced Search: Advanced Word Finder: See Also in English. [129] In breeding grounds, codas are almost entirely produced by adult females. [72], The sperm whale has the longest intestinal system in the world,[73] exceeding 300 m in larger specimens. [200][201] However, male sperm whales have been observed to attack and intimidate killer whale pods in competitive feeding instances. The sperm whale is one of the species originally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. [193] Early whalers exploited this behaviour, attracting a whole unit by injuring one of its members. The Origin of the “Sperm Whale” Name: Bad Misunderstanding The name sperm whale, short for spermaceti whale , became mainstream at the end of the 18th century. "[195], If the killer whale pod is large, its members may sometimes be able to kill adult female sperm whales and can at least injure an entire pod of sperm whales. ‘They live in very deep waters, at about 500 metres and below, and provide fodder for the sperm whale.’ ‘And I marvelled at the museum's centre-piece - a 55-foot long skeleton of a sperm whale, which would have weighed more than 20 tons when it was alive.’ ‘In 1820, a sperm whale sunk an American whaler 2,000 km from land.’ Such beaks precipitate the formation of ambergris. [208][217][218], These analyses also confirm that there was a rapid evolutionary radiation (diversification) of the Physeteroidea in the Miocene period. [74][75] Similar to ruminants the sperm whale has a four-chambered stomach. Verne portrays them as being savage hunters ("nothing but mouth and teeth"). By contrast, the auditory system is enlarged. However, sperm whale ivory contains a much thicker inner layer. Like walrus ivory, sperm whale ivory has two distinct layers. There is no costocervical artery. It has been estimated to weigh 80 tonnes (79 long tons; 88 short tons). [159], An older study, examining whales captured by the New Zealand whaling fleet in the Cook Strait region, found a 1.69:1 ratio of squid to fish by weight. [28] Experts soon realised that just one such species exists, although there has been debate about whether this should be named P. catodon or P. macrocephalus, two of the names used by Linnaeus. [241] Whale ivory and bone were taken from beached whales. A continuous fat-filled canal transmits received sounds to the inner ear. 359–367 in. One study published in 2010 collected evidence that suggests that female sperm whales may collaborate when hunting Humboldt squid. [9], 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. [9] Sexually mature females give birth once every 4 to 20 years (pregnancy rates were higher during the whaling era). [36] In 1853, one sperm whale was reported at 62 feet (19 m) in length with a head measuring 20 feet (6.1 m). Video footage has been captured of a large male sperm whale "bouncing" a long line, to gain the fish. Some say Tangaroa (god of the sea) is the ancestor of sea creatures, while others name Te Pūwhakahara, … (As far as we can tell, Moby Dick was the only sperm whale that delivered a unique brand of karmic justice to one-legged sea captains bent on vengeance.) The purpose of this complex is to generate powerful and focused clicking sounds, which the sperm whale uses for echolocation and communication. [237], The total number of sperm whales in the world is unknown, but is thought to be in the hundreds of thousands. In that year, however, Dutch zoologists Antonius M. Husson and Lipke Holthuis proposed that the correct name should be P. macrocephalus, the second name in the genus Physeter published by Linnaeus concurrently with P. catodon. [86][87][88] The spermaceti organ may also play a role by adjusting buoyancy (see below). Sperm whales are present in every ocean, and after humans and orca, are the most widely distributed mammal on earth. [202] However, at some potential feeding sites, the killer whales may prevail over sperm whales even when outnumbered by the sperm whales. [236], Remaining sperm whale populations are large enough that the species' conservation status is rated as vulnerable rather than endangered. Instead, sloops concentrated on the Nantucket Shoals, where they would have taken right whales or went to the Davis Strait region to catch bowhead whales. The fleet's scope and size increased over time, and larger ships entered the fishery. [252], The introduction of plastic waste to the ocean environment by humans is relatively new. [63][66], The sperm whale's cerebrum is the largest in all mammalia, both in absolute and relative terms. Lack of prey?] A piece of the posterior wall of the frontal sac. [121], When echolocating, the sperm whale emits a directionally focused beam of broadband clicks. Upon reaching sexual maturity, males move to higher latitudes, where the water is colder and feeding is more productive. The cornea is elliptical and the lens is spherical. This back and forth reflection which happens on the scale of a few milliseconds creates a multi-pulse click structure. But strike a member of the harem school, and her companions swim around her with every token of concern, sometimes lingering so near her and so long, as themselves to fall a prey. [80], Atop the whale's skull is positioned a large complex of organs filled with a liquid mixture of fats and waxes called spermaceti. There is a huge variance in the size of social units. [149] Along the Korean Peninsula, the first confirmed observation within the Sea of Japan, eight animals off Guryongpo, was made in 2004 since after the last catches of five whales off Ulsan in 1911,[139][150] while nine whales were observed in the East China Sea side of the peninsula in 1999. [173], Sperm whales can live 70 years or more. [citation needed] Between 184,000 and 236,000 sperm whales were killed by the various whaling nations in the 19th century,[234] while in the 20th century, at least 770,000 were taken, the majority between 1946 and 1980. [156] Most of what is known about deep-sea squid has been learned from specimens in captured sperm whale stomachs, although more recent studies analysed faeces. [176], Females become fertile at around 9 years of age. [187], When sperm whales socialize, they emit complex patterns of clicks called codas. What does being anoxic have to do with whales that don't breath under water? 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. The specific name macrocephalus is Latinized from the Greek makrokephalos (μακροκέφαλος, meaning "big-headed"), from makros (μακρός, "large") + kephalē (κεφαλή, "head"). The hunting led to the near-extinction of large whales, including sperm whales, until bans on whale oil use were instituted in 1972. It is also covered by the Agreement on the Conservation of Cetaceans in the Black Sea, Mediterranean Sea and Contiguous Atlantic Area (ACCOBAMS) and the Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region (Pacific Cetaceans MOU). 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.[188][189]. [157] Battles between sperm whales and giant squid or colossal squid have never been observed by humans; however, white scars are believed to be caused by the large squid. [70] On average, females and juveniles blow every 12.5 seconds before dives, while large males blow every 17.5 seconds before dives. [167], 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 in oysters. 30 teeth of the sperm whale can be used for ivory. The whale’s spermaceti organ and blubber also hold sperm oil, a pale yellow oil that was used as a superior lighting oil and later as a lubricant and in soap manufacturing. They are most commonly between six and nine individuals in size but can have more than twenty. It is suggested that the whales can see the squid silhouetted above them against the dim surface light. Experts soon realized that just one such species exists. In New Zealand, the Māori know them as "rei puta"; such whale tooth pendants were rare objects because sperm whales were not actively hunted in traditional Māori society. These evolutionary modifications make the spine more flexible but weaker than the spines of terrestrial vertebrates.[55]. Lack of prey? They inhabit the Mediterranean Sea, but not the Black Sea,[9] while their presence in the Red Sea is uncertain. There are three species, the Sperm Whale, the Dwarf Sperm Whale and the Pygmy Sperm Whale. [104] The speed of sound in spermaceti is 2,684 m/s (at 40 kHz, 36 °C), making it nearly twice as fast as in the oil in a dolphin's melon. sperm whale's eyes afford good vision and sensitivity to light. [238] The International Union for Conservation of Nature (IUCN) regards the sperm whale as being "vulnerable". [40] Bulls have beached themselves together, suggesting a degree of cooperation which is not yet fully understood. [213] Genera from the Oligocene and early and middle Miocene, with the possible exception of Aulophyseter, had teeth in their upper jaws. [49] The whale lifts its flukes high out of the water as it begins a feeding dive. The females will protect their calves or an injured adult by encircling them. sperm whale definition: 1. a large whale with a very large, long head 2. a large whale with a very large, long head. Male sperm whales are physically mature at about 16 metres (52 ft) in length and generally reaching a maximum of about 18 to 19 meters (59 to 62 ft). By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Meaning of sperm whale. In reality, even the largest whales only ejaculate up to a few gallons of semen at a time, and this ejaculate has nothing to do with the saltiness of the ocean. At the posterior end of this spermaceti complex is the frontal sac, which covers the concave surface of the cranium. [248] It was selected because of its specific contribution to the state's history and because of its present-day plight as an endangered species. The head of the sperm whale contains an enormous fluid-filled organ (which whalers called the case). [35], The sperm whale is the largest toothed whale, with adult males measuring up to 20.7 metres (68 ft) long and weighing up to 80 tonnes (79 long tons; 88 short tons). Pilot Whale Meaning. Modern whaling was more efficient than open-boat whaling, employing steam-powered ships and exploding harpoons. The iron-rich faeces cause phytoplankton to grow and take up more carbon from the atmosphere. Linnaeus recognized four species in the Physetergenus (Linnaeus 1758). However, due to the distinctive look and large size of the whale, watching is increasingly popular. 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. [89] The arterial retia mirabilia are extraordinarily well-developed. [16] The word cachalot came to English via French from Spanish or Portuguese cachalote, perhaps from Galician/Portuguese cachola, "big head". (2004). The dwarf sperm whale (Kogia sima) is a sperm whale that inhabits temperate and tropical oceans worldwide, in particular continental shelves and slopes.It was first described by biologist Richard Owen in 1866, based on illustrations by naturalist Sir Walter Elliot.The species was considered to be synonymous with the pygmy sperm whale (Kogia breviceps) from 1878 until 1998. Each spring, sperm whales gather in waters over canyons up to 1,000 metres deep to mate. Spermaceti is the semi-liquid, waxy substance found in the animal's head. [80] Their circulatory system has adapted to dive at great depths, as much as 2,250 metres (7,382 ft)[6][7][81][82][83] for up to 120 minutes. [228][231][232] Hunting could be dangerous to the crew, since sperm whales (especially bulls) will readily fight to defend themselves against attack, unlike most baleen whales. Its surrounding wall, known as the case, is extremely tough and fibrous. When the whale is submerged, it can close the blowhole, and air that passes through the phonic lips can circulate back to the lungs. pakake – minke whale; parāoa – sperm whale; ūpokohue – blackfish or pilot whale. Bones show the same pitting that signals decompression sickness in humans. It is the only living member of the genus Physeter and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia. The sperm whale's distinctive shape comes from its very large, block-shaped head, which can be one-quarter to one-third of the animal's length. [212] Most sperm whale fossils date from the Miocene period, 23 to 5 million years ago. [194] Such a tactic is described in Moby-Dick: "Say you strike a Forty-barrel-bull—poor devil! [163] In one case, three sperm whales were observed attacking or playing with a megamouth. Rudimentary teeth are also present in the upper jaw, but these rarely emerge into the mouth. [229][230] Sperm whaling in the 18th century began with small sloops carrying only one or two whaleboats. Historical catch records suggest there could have been smaller aggression grounds in the Sea of Japan as well. The S-shaped blowhole is located very close to the front of the head and shifted to the whale's left. There are no ciliary muscles. [167][253][254][255], "Cachalot" redirects here. [130] Large males are generally solitary and rarely produce codas. A mature sperm whale has few natural predators, although calves and weakened adults are sometimes killed by pods of killer whales (orcas). At birth both sexes are about the same size,[9] but mature males are typically 30% to 50% longer and three times as massive as females. Such coastal groups were more abundant in pre-whaling days. [243] Today the tabua remains an important item in Fijian life. I changed the position of the creatures skeleton to have the head part of the Whale to be inside of the bounding box so you'll have to hit its head to cause any damage. Romances of Adventure. Whalers likened the substance to semen, and this is the origin of the common name of the species. Sperm whales are prodigious feeders and eat around 3% of their body weight per day. Spermaceti, a wax, liquid at body temperature, obtained from the head of a sperm whale or bottlenose whale. The name sperm whale is a truncation of spermaceti whale. Swedish ichthyologist Peter Artedi described it as Physeter catodon in his 1738 work Genera piscium, from the report of a beached specimen in the Orkneys in 1693 and two beached in the Netherlands in 1598 and 1601. [200][203], Sperm whales are not known for forging bonds with other species, but it was observed that a bottlenose dolphin with a spinal deformity had been accepted into a pod of sperm whales. [177] Birth is a social event, as the mother and calf need others to protect them from predators. [134] The Black Sea's lower layers are also anoxic and contain high concentrations of sulphur compounds such as hydrogen sulphide. [123][124] Because the interval between pulses of a sperm whale's click is related to the length of the sound producing organ, an individual whale's click is unique to that individual. [174][175] Bulls do not provide prenatal care to their offspring but rather play a fatherly role to younger bulls to show dominance. Sperm whale watchers often use hydrophones to listen to the clicks of the whales and locate them before they surface. [53] While sperm whales are well adapted to diving, repeated dives to great depths have long-term effects. [249], Sperm whales are not the easiest of whales to watch, due to their long dive times and ability to travel long distances underwater. A 2008 study published in Current Biology recorded evidence that whales may sleep with both sides of the brain. 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. More Russian words for sperm whale. [113] A few famous instances include the well-documented sinking of the ships Essex and Ann Alexander by attackers estimated to weigh only one-fifth as much as the ships.[106]. [212][213] Orycterocetus fossils have also been found in the North Atlantic Ocean and the Mediterranean Sea, in addition to the west coast of the United States. The sperm whale was designated as the Connecticut state animal by the General Assembly in 1975. 3D print model Sperm Whale Tooth, formats STL, 3d art biology form ghosts gifts, ready for 3D animation and other 3D projects Tags art whaletooth sperm reprap ghosts tooth tongarewa massey print biology form papa free gifts masseyuniversity pla whale science university wellington newzealand sculpture [26][212], Fossil sperm whales differ from modern sperm whales in tooth count and the shape of the face and jaws. [9] Another view holds that exploitation by overwhaling had virtually no effect on the size of the bull sperm whales, and their size may have actually increased in current times on the basis of density dependent effects. Inside Natures Giants: The Sperm Whale. Jefferson, T. A., Stacey, P. J., & Baird, R. W. (1991). Older skeletons showed the most extensive pitting, whereas calves showed no damage. The females cooperate to protect and nurse their young. [155] They feed on several species, notably the giant squid, but also the colossal squid, octopuses, and fish such as demersal rays, but their diet is mainly medium-sized squid. Your feedback will go directly to Science X editors. Spermaceti, obtained primarily from the spermaceti organ, and sperm oil, obtained primarily from the blubber in the body, were much sought after by 18th, 19th, and 20th century whalers. The spermaceti organ is unique to sperm whales, although bottlenose whales possess a similar organ. Probably the most famous sperm whale was Moby Dick, the great white whale from Herman Melville’s classic novel of the same name. [177] The oldest pregnant female ever recorded was 41 years old. The olfactory system is reduced, suggesting that the sperm whale has a poor sense of taste and smell. 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,[114] but are unable to roll the eyes in their sockets.[115]. dfo-mpo.gc.ca Son crâne renferme une réserve de spermaceti, sorte de cire huileuse qui était très prisée par les baleiniers. Due to games limitations, I can't change the bounding box to accommodate a massive creature such as a Sperm Whale. Sperm whales gather off Sri Lanka in great number - at least 100, perhaps many more. Herman Melville", "What is a Whale? The sclera is very hard and thick, roughly 1 cm anteriorly and 3 cm posteriorly. [138][139] followed by one on Ganghwa Island in 2009. Females remain at lower latitudes. [179], Lactation proceeds for 19 to 42 months, but calves, rarely, may suckle up to 13 years. [122] This multi-pulse click structure allows researchers to measure the whale's spermaceti organ using only the sound of its clicks. The sperm whale got its name from an oil-like wax in its head, called spermaceti, which was prized by whalers. [85] The blood has a high density of red blood cells, which contain oxygen-carrying haemoglobin. Beachcombers look out for ambergris as flotsam. sperm count definition: 1. the number of live male sperm cells in a particular amount of the liquid in which they are…. The knobbly surface reflects sound waves that come through the spermaceti organ from the phonic lips. [101] It is proportionately larger in males. This was during the time when whaling was conducted commercially. The total annual consumption of prey by sperm whales worldwide is estimated to be about 91 million tonnes (100 million short tons). Russian Translation. The most common natural predator of sperm whales is the killer whale, but pilot whales and false killer whales sometimes harass them. [161] However, the amount of fish taken is very little compared to what the sperm whale needs per day.
