Size / Weight / Age
Max length : 610 cm TL male/unsexed; (Ref. 1394); 550 cm TL (female); max. published weight: 3.6 t (Ref. 1394)
Pelagic; non-migratory (Ref. 75906); depth range 0 - 1000 m (Ref. 1005), usually 600 - 1000 m (Ref. 104603)
Climate / Range
Tropical; 15°C - 16°C (Ref. 97344); 90°N - 90°S, 180°W - 180°E
Atlantic Ocean and Indo-Pacific. Tropical and warm temperate.
Maximum depth from Ref. 104603. Found in deep offshore areas. Feeds on squid, sometimes fish (Ref. 936). Length at first maturity ranges from 310 to 400 cm for females and 390 to 590 cm for males (Ref. 75819). Found in deep offshore areas. Feeds on squid, sometimes fish (Ref. 936). They are gregarious, rarely found solitary (Ref. 114960). 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).
IUCN Red List Status (Ref. 114614)
