Environment: milieu / climate zone / depth range / distribution range
Ecology
Pelagic; non-migratory (Ref. 75906); depth range 0 - 2418 m (Ref. 116169), usually 600 - 1000 m (Ref. 104603). Tropical; 15°C - 16°C (Ref. 97344); 90°N - 90°S, 180°W - 180°E
Atlantic Ocean and Indo-Pacific. Tropical and warm temperate.
Length at first maturity / Size / Weight / Age
Maturity: Lm 316.0, range 290 - 400 cm Max length : 610 cm TL male/unsexed; (Ref. 1394); 550 cm TL (female); max. published weight: 3.6 t (Ref. 1394)
Found in deep offshore areas (Ref. 936, 122680). Their main foraging grounds are those with high density of squid (Ref. 122680), its primary food. Sometimes feeds on fish (Refs. 936, 122680) and octopus (Ref. 122680). They are gregarious, rarely found solitary (Ref. 114960).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Males mature later than females because of their size and polygynous breeding behavior. Breeding longevity of Pacific species lasts for 17 to 31 years. Those less than 24 years old have a relatively high reproductive potential and longer resting period (Ref. 97344).
