About Abudefduf abdominalis (Quoy & Gaimard, 1825)
Abudefduf abdominalis, common names green damselfish, Hawaiian sergeant major, and maomao, is a non-migratory fish species in the family Pomacentridae. It is found in the Pacific Ocean, in waters near the Hawaiian Islands, Midway Island, and Johnston Atoll. This species can reach a maximum total length of 30 centimetres (12 inches). Adult Abudefduf abdominalis typically inhabit quiet, rocky-bottomed waters in inshore and offshore reefs, at depths between 1 metre (3 feet 3 inches) and 50 metres (164 feet 1 inch). Juveniles of the species may occasionally be found in surge pools. It is a benthopelagic species, and adult individuals are known to form schools. The species feeds on a range of algae and zooplankton. It is used as a food source for humans in Hawaii, and it occasionally appears in the aquarium trade.
