The green damselfish (Abudefduf abdominalis),[3] also known as the Hawaiian sergeant major, is a non-migratory (lives always in the same area) fish of the family Pomacentridae. It occurs in the Pacific Ocean in near the Hawaiian Islands, Midway Island and Johnston Atoll.[1] It can grow to a maximum total length of 30 cm (11.8 inches).

Adults of the species are typically found in quiet waters with rocky bottoms in inshore and offshore reefs at a depth of 1 to 50 m (3 to 164 ft), although juveniles (young fish) may sometimes be found in surge pools. It is a benthopelagic species, with adults being known to form schools (large groups). The species feeds on a variety of algae and zooplankton and is oviparous, with distinct pairing occurring during breeding. Eggs of Abudefduf abdominalis are demersal (bottom feeders) and adhere to the ground ?(substrate), with males guarding and aerating (giving air) the eggs. The species is known to be used as a food source for humans in Hawaii.[2] It occasionally appears in the aquarium trade.[1]
