Largest sperm whale (Ref. 1394). Sperm whaling has a long history. The most intense periods were the Yankee whaling era of the 1800s and the factory ship whaling of the 20th century. Recent findings of studies on social behavior and breeding undermine assumptions in the models on which exploitation and management have long been based. Certain populations have been depleted, but the sperm whale remains the most abundant of all the great whales (Great whales generally include the sperm whale and all baleen whales, except the pygmy right whale) (Ref. 1394). Maximum size of female species based from Ref. 1394. Deep divers. Feeds on squids, octopuses (Ref. 1394), sharks, demersal rays, and bony fishes (Ref. 122680). Forms strong social bonds (Ref. 122680). Feeding strategy involves synchronized, individual hunting for non-schooling prey such as deep-sea squids (Ref. 130961).
Mature females live in socially cohesive groups of 10-30 individuals which include immature males and females and within is a communal suckling and caring of the young. Also, males leave the group at the age of 6 (Ref. 97765).
