Description of life cycle and mating behavior Pelagic spawner. Females migrate to spawning sites, larger females travel long distances to downcurrent areas than smaller ones to protect the eggs from becoming prey to larger reef fishes (Ref. 32198). Spawning sites are chosen by the females irregardless of the males occupying them (Ref. 32198). Females spawn in more than one spawning site, each site occupied by more than one male, which are either territorial or non-territorial (Ref. 32198). After spawning, they return individually to their home ranges without passing through other spawning sites (Ref. 32198). Some females on the other hand change sex after spawning (Ref. 32198). As males, they begin to establish territories in the spawning sites, even to those they visited before the sex change (Ref. 32198). This observation support the suggestion (Warner's 1985, 1986) that females stored information on spawning sites by migrating to various sites which aided in the acquisition of a mating territory after changing sex (Ref. 32198).
