Description of life cycle and mating behavior The pelagic-broadcast spawning behavior consisted of males pursuing a single female and nudging her abdominal region. When the female was ready to spawn, a single male wrapped around the female at which time eggs and milt were simultaneously expelled. Reproduction usually consisted of several individual spawning episodes with at least 10-min intervals between events (Ref. 35784).
