sperm whale (Physeter Macrocephalus)

The biggest carnivore in the world because the male can reach up to 20 metres in length, this cetacean is the last representative of his family, Physeteroidea, with the pygmy and dwarf sperm whales. It is known for its apnoea diving records, reaching depths of three thousand metres, a record unequalled among mammals. The males are the only ones to risk entering the icy waters of the Arctic and Antarctic. Little is still known about the sperm whale.
