Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
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).
