The sperm whale is a pelagic mammal with a worldwide range, and will migrate seasonally for feeding and breeding. [ 5 ] Females and young males live together in groups, while mature males (bulls) live solitary lives outside of the mating season. The females cooperate to protect and nurse their young.
Cetacea (/ sɪˈteɪʃə /; from Latin cetus ' whale ', from Ancient Greek κῆτος (kêtos) ' huge fish, sea monster ') [ 3 ] is an infraorder of aquatic mammals belonging to the suborder Whippomorpha that includes whales, dolphins and porpoises. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size ...
A 2008 study found that sperm whales sleep in vertical postures just under the surface in passive shallow "drift-dives", generally during the day, during which whales do not respond to passing vessels unless they are in contact, leading to the suggestion that whales possibly sleep during such dives. [71]
Scientists studying the sperm whales that live around the Caribbean island of Dominica have described for the first time the basic elements of how they might be talking to each other, in an effort ...
Cetacean surfacing behaviour is a grouping of movement types that cetaceans make at the water's surface in addition to breathing. Cetaceans have developed and use surface behaviours for many functions such as display, feeding and communication. All regularly observed members of the order Cetacea, including whales, dolphins and porpoises, show a ...
The dwarf sperm whale is a small whale, 2 to 2.7 m (6 ft 7 in to 8 ft 10 in) and 136 to 272 kg (300 to 600 lb), that has a grey coloration, square head, small jaw, and robust body. Its appearance is very similar to the pygmy sperm whale, distinguished mainly by the position of the dorsal fin on the body–nearer the middle in the dwarf sperm ...
Spermaceti. Left to right: A sample of solid raw spermaceti, a spermaceti wax candle and a bottle of sperm oil. Spermacetispɜːməˈsiːti is a waxy substance found in the head cavities of the sperm whale (and, in smaller quantities, in the oils of other whales). Spermaceti is created in the spermaceti organ inside the whale's head.
Scientists have accomplished a whale of a feat. They’ve identified previously unknown complexity in whale communication by analyzing thousands of recorded sequences of sperm whale clicks with ...
