Sperm whale

Sperm whale (Physeter macrocephalus) is a largest toothed whale (odontocete) species. A bull can grow up to 20.5 metres long.
Sperm whale is among the most cosmopolitan species. It prefers ice-free waters over 1,000 metres deep. Although both sexes range through temperate and tropical oceans and seas, only adult males populate higher latitudes. Sperm whales often occur in the deep waters of Commander Islands, but only males were encountered to date, though several strandings of juveniles were observed, including a stranding of 1-year old female in January 2010. Sperm whales feed mostly on squid, diving as deep as 3 kilometres, which makes it the deepest diving mammal. The sperm whale's clicking vocalization is the loudest sound produced by any animal.
