Life cycle and mating behavior
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
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).
