Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 12; членистые (мягкие) лучи спинного плавника (общее число) : 15 - 16; колючие лучи анального плавника: 2; членистые (мягкие) лучи анального плавника: 15 - 16. Closely related D. trimaculatus, which does not occur in the Hawaiian Islands and Johnston Island.
Adults are found in very shallow, protected water, over coral and rocky bottoms. Young often sheltering among the branches of Pocillopora; occasionally commensal with the anemone Marcanthia cookei (Ref. 9710). Benthopelagic (Ref. 58302). Peak spawning from May to August. Age-at-maturity estimated at one year. Feed on zooplankton, benthic invertebrates, and algae (Ref. 9710). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Have been reared in captivity (Ref. 35412).
Life cycle and mating behavior
половая зрелость | размножение | нерест | икра | Fecundity | личинки
Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). While protogyny was originally proposed for this species, recent studies confirmed gonochorism in the form of non-functional hermaphroditism (Ref. 103751).
