It’s estimated that sperm whales can hear one another hundreds, perhaps even thousands of miles away using this technique. , 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. Author information: (1)Department of Zoophysiology, Arhus University, Denmark. (The production of sound is similar to air passing through the neck of a balloon.) Purves, M. G., Agnew, D. J., Balguerias, E., Moreno, C. A., & Watkins, B. A sperm whale's click is almost over before it starts. , The source of the air forced through the phonic lips is the right nasal passage. The other adults may jostle and bite the newborn in its first hours. Inside Natures Giants: The Sperm Whale. "Whale Dies on N.C. beach" Associated Press. Only 8 out of 21 sailors survived to be rescued by other ships.. Outside breeding grounds, slow clicks are rarely heard, and usually near the surface. 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.  In Asian waters, whales are also observed regularly in coastal waters in places such as the Commander and Kuril Islands, Shiretoko Peninsula which is one of few locations where whales can be observed from shores, off Kinkasan, vicinity to Tokyo Bay and the Bōsō Peninsula to the Izu and the Izu Islands, the Volcano Islands, Yakushima and the Tokara Islands to the Ryukyu Islands,Taiwan, the Northern Mariana Islands, and so forth. , The largest animal weighed in whole was a sperm whale which measured 18 metres (59 ft) long and weighed 53 tonnes (52 long tons; 58 short tons). Møhl B(1), Wahlberg M, Madsen PT, Miller LA, Surlykke A.  followed by one on Ganghwa Island in 2009. , These analyses also confirm that there was a rapid evolutionary radiation (diversification) of the Physeteroidea in the Miocene period. There is no costocervical artery. Evolutionary family tree of sperm whales. ", 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. Physeter macrocephalus The vocalizations of the sperm whale (Physeter macrocephalus) are made by very brief impulsive sounds, called clicks, organized in variable length sequences.These clicks generally reach 30-35 kHz in frequency with repetition rates of 2-3 clicks per second. Sperm whales are highly vocal, producing distinct types of clicks for both echolocation and social interaction purposes.  Whale ivory and bone were taken from beached whales.  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..  The structure of the junk redistributes physical stress across the skull and may have evolved to protect the head during ramming..  It has the largest brain on Earth, more than five times heavier than a human's.  Gestation requires 14 to 16 months, producing a single calf. The sound can be used to track squid just a foot in length up to a mile away. Lack of prey?] Sperm whale, the largest of the toothed whales, easily recognized by its enormous square head and narrow lower jaw. The International Whaling Commission gave the species full protection in 1985, but hunting by Japan in the northern Pacific Ocean continued until 1988. Such coastal groups were more abundant in pre-whaling days. Herman Melville", "What is a Whale? After World War II, whaling continued unabated to obtain oil for cosmetics and high-performance machinery, such as automobile transmissions. When dealing with a threat, sperm whales will use their huge head effectively as a battering ram. One study, carried out around the Galápagos, found that squid from the genera Histioteuthis (62%), Ancistrocheirus (16%), and Octopoteuthis (7%) weighing between 12 and 650 grams (0.026 and 1.433 lb) were the most commonly taken.  Killer whales prey on target groups of females with young, usually making an effort to extract and kill a calf. The choroid is very thick and contains a fibrous tapetum lucidum. According to Fristrup and Harbison (2002),  Most squid beaks are vomited by the whale, but some occasionally make it to the hindgut. ), usually found at the sea floor, in its belly.  This gives rise to a distinctive bushy, forward-angled spray.  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. , A creak is a rapid series of high-frequency clicks that sounds somewhat like a creaky door hinge.  The first ever record on the west coast of the Korean Peninsula (Yellow Sea) was made in 2005. The colossal toothed whales pass air through nasal passages which is subsequently forced through two lips called “monkey lips” at the front of its nose just below the blowhole. They can emit a click at around 230 decibels, considerably louder than a jet engine at around 150db. 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.  Today, males do not usually exceed 18.3 metres (60 ft) in length or 51 tonnes (50 long tons; 56 short tons) in weight. Socializing usually takes place in the afternoon.
