Mammalia | Cetacea
Environment: milieu / climate zone / depth range / distribution range
Pelagic; oceanodromous (Ref. 75906); depth range 0 - 3200 m (Ref. 1005), usually 500 - 500 m (Ref. 75906). Tropical; 90°N - 90°S, 180°W - 180°E
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 830 - 920 cm Max length : 2,400 cm TL male/unsexed; (Ref. 99323); 1200 cm TL (female); max. published weight: 57.0 t (Ref. 1394)
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). 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).
