DetailsSperm whale _Designed by YahooJAPAN ( http://www.thingiverse.com/thing:182337 ) _Sperm whale (Physeter catodon), also called cachalot, the largest of the toothed whales, easily recognized by its enormous square head and narrow lower jaw. The sperm whale is dark blue-gray or brownish, with white patches on the belly. It is thickset and has small paddlelike flippers and a series of rounded humps on its back. Males attain a maximum length of about 19 metres (62 feet) and females about 12 metres. _Sperm whales are deep divers, commonly reaching a depth of about 350 metres, and have been found tangled in cables more than 1,000 metres below the surface. It is not uncommon for sperm whales to dive for an hour or more and then spend about 10 minutes at the surface breathing once every 10 seconds. They can cruise at a speed of 4 knots (7.4 km/hr; 4.6 mph) and swim in spurts at up to 20 knots. _These cetaceans are found in temperate and tropical waters throughout the world, usually in pods (groups) of about 15 to 20; solitary males, however, may wander into colder regions. Sperm whales attain sexual maturity at 7 to 13 years of age and physical maturity at 25 to 45 years and have been recorded to live as long as 62 years. They feed primarily on cephalopods, including the giant squid (Architeuthis dux). Weight figures are usually estimates, but in 1937 a pair of stranded male sperm whales were measured intact in the Netherlands: one was 16 metres long and weighed 39 tons, and the other was 18 metres and 53 tons. _The sperm whale is the most evolutionarily modified of the toothed whales. The head constitutes one-third of the total body length and, it is estimated, greater than a third of the body weight. The lower jaw is usually equipped with 36 to 50 large conical teeth; the upper jaw holds a variable number of vestigial teeth that do not erupt. The head features an elaborately developed nose and upper lip where the fluid-filled spermaceti organ (which whalers called the case) is located; sperm oil and spermaceti were extracted from this fluid for lighting and lubrication. The spermaceti organ is unique to sperm whales. It has a volume as large as 2,000 litres (530 gallons) and can extend through 40 percent of the whale’s length. _Sperm whales were once commercially valuable and were hunted for several centuries. The White Whale hunted in Herman Melville’s novel Moby Dick (1851) is presumably an albino sperm whale. Ambergris, a material sometimes found floating in the sea, is thought to be formed in the sperm whale’s intestines around a core of undigested solid matter such as squid beaks.
