Transient migration (Ref. 8689). Lives in matrilines throughout their lifetime (Ref. 97337). Commonly found in nearshore, cold temperate to subpolar waters (Refs. 1394, 936). Forms large social groups and strong social bonds. Feeds cooperatively (Ref. 122680). Feeds on sharks, large baleen whales (Ref. 122680), all oceanic cetaceans, pinniped, penguins, and other seabirds, leatherback turtles, squid and many types of fish (Refs. 1394, 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).
