Sperm whales are usually found in deep, off-shore waters, but may be seen closer to shore, in areas where the continental shelf is small and drops quickly to depths of 310 to 920 metres (1,020 to 3,020 ft). [11] Coastal areas with significant sperm whale populations include the Azores and Dominica. [142]
[28] [12] Between dives, the sperm whale surfaces to breathe for about eight minutes before diving again. [29] Odontoceti (toothed whales) breathe air at the surface through a single, S-shaped blowhole, which is extremely skewed to the left. Sperm whales spout (breathe) 3–5 times per minute at rest, increasing to 6–7 times per minute after ...
Although Dwarf sperm whales swim in the deep waters far from the shore, they still possess some important escaping mechanisms. “If a Dwarf sperm whale is frightened, it may secrete a red liquid. This causes a cloud to form that stops or distracts predators. This allows the whale to dive deep into the ocean and escape” (Petrie, 2005).
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 ...

Sperm whales, which can reach about 60 feet (18 meters) long, have the largest brain of any animal. They are deep divers, feeding on giant squid and other prey.
Some rorquals can dive for up to 40 minutes, sperm whales between 60 and 90 minutes and bottlenose whales for two hours. Diving depths average about 100 m (330 ft). Species such as sperm whales can dive to 3,000 m (9,800 ft), although more commonly 1,200 metres (3,900 ft). [57] [58]
[34]: 96 Most cetaceans live in the open ocean, and species like the sperm whale may dive to depths of −1,000 to −2,500 feet (−300 to −760 m) in search of food. [35] Sirenians live in shallow coastal waters, usually living 30 feet (9.1 m) below sea level.
