Etymology: Abudefduf: Arabic, abu = father; this fish is the leader of the reef against other species (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 1 - 50 m (Ref. 9710). Tropical; 29°N - 18°N, 178°W - 151°W (Ref. 56014)
Eastern Central Pacific: Midway Islands (Ref. 7247) and Hawaii southward to central Polynesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 9710)
soft rays: 13 - 15. Similar to A. bengalensis but has fewer vertical stripes, a black blotch on the posterior base of the dorsal and anal fins, and pointed caudal fin lobes.
Found in quiet waters with rocky bottoms in inshore and offshore reefs; juveniles sometimes found in surge pools (Ref. 205). Benthopelagic (Ref. 58302). Adults form school. Feed on a variety of algae and zooplankton. 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). Used as food by the Hawaiians (Ref. 7364).
