Sergeant-Major

Abudefduf saxatilis

Sergeant-Major

Bold black bars give the sergeant major its name as it grazes shallow reef tops and gathers in feeding crowds of hundreds. It takes algae, small crustaceans, fish, and larvae, and at one island it even eats the leavings of spinner dolphins. Males guard purple egg patches on the rock.
