Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Pelagic spawner. This species exhibits a combination of simultaneous and sequential hermaphroditism. Smaller individuals within a social group are simultaneous hermaphrodites, while the largest often lose female function and reproduce exclusively as a male (Ref. 103751).
