Etymology: Abudefduf: Arabic, abu = father; this fish is the leader of the reef against other species (Ref. 45335).

Indo-Pacific: Red Sea and eastern Africa to the Line and Tuamoto islands, north to southern Japan, south to Australia. Recorded in Bay of Islands, New Zealand (Ref. 35942). Often confused with the closely related Atlantic species Abudefduf saxatilis (Ref. 7247). Replaced by Abudefduf abdominalis in the Hawaiian Islands (Ref. 37816).
Adults inhabit upper edge of outer reef slopes and inshore rocky reefs. Juveniles associated with drifting seaweed (Ref. 12114, 12115). Benthopelagic (Ref. 58302). Feed on zooplankton, benthic algae, and small invertebrates (Ref. 1602). Often in aggregations (Ref. 9710) feeding at midwater or tending nests among rocks and coral ledges (Ref. 90102). In large numbers at spawning sites that are timed with large tides that carry their pelagic offspring far offshore (Ref. 48636). 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).
