Size / Weight / Age
Max length : 980 cm TL male/unsexed; (Ref. 1394); 850 cm TL (female); max. published weight: 10.0 t (Ref. 1394)
Pelagic; oceanodromous (Ref. 75906); depth range 0 - 2450 m (Ref. 102388)
Climate / Range
Tropical; 90°N - 90°S, 180°W - 180°E
Circumglobal. Climate: cosmopolitan.
Commonly found in nearshore, cold temperate to subpolar waters. Feeds on all oceanic cetaceans, pinniped, penguins, and other seabirds, leatherback turtles, squid and many types of fish (Refs. 1394, 936). Transient migration (Ref. 8689). Length at first maturity ranges from 570 to 660 cm for females and 670 to 800 cm for males (Ref. 75906). Lives in matrilines throughout their lifetime (Ref. 97337). Commonly found in nearshore, cold temperate to subpolar waters. Feeds on all oceanic cetaceans, pinniped, penguins, and other seabirds, leatherback turtles, squid and many types of fish (Ref. 1394 and 936). Polygamous (Ref. 8653). Sexually dimorphic; males are larger than females (Ref. 97315). Females have higher preference for non-pod males that arrive as part of a matriline than males that arrive alone. Multiple mating occurs based on testis size to body size ratios; females mate with more than one male during associations between pods (Ref. 97337). Calving is diffusely seasonal, with a peak in autumn for northeastern Pacific species (Ref. 97343).
