    Species: Abudefduf saxatilis
    Class: C
    Synonyms: Abudefduf ascensionis, Abudefduf caudobimaculatus, Abudefduf coelestinus, Abudefduf marginatus, Abudefduf saxiatilis, Abudefduf septemfasciatus, Abudefduf sexatilis, Abudefduf vaigiensis, Apogon quinquevittatus, Chaetodon marginatus, Chaetodon mauritii, Chaetodon sargoides, Chaetodon saxatilis, Glyphidodon saxatilis, Glyphisodon biniar, Glyphisodon moucharra, Glyphisodon rahti, Glyphisodon vaigiensis
    Environment: Reef-associated; non-migratory; marine; depth range 0 - 20 m
    Size/Weight/Age: Max length : 22.9 cm TL male/unsexed; (Ref. 26340 ); common length : 15.0 cm SL male/unsexed; max. published weight: 200 g
    Distribution: Atlantic Ocean: Canada (Ref. 5951 ) to Rhode Island, USA to Uruguay in the western Atlantic, abundant on Caribbean reefs; around islands of the mid-Atlantic, Cape Verde, and along the tropical coast of western Africa south to Angola. This species is strictly an Atlantic species. It is replaced in the Indo-Pacific region by the closely related Abudefduf vaigiensis (G. Allen, pers. comm.).
    Description: Dorsal spines (total): 13; Dorsal soft rays (total): 12 - 13; Anal spines: 2; Anal soft rays: 10 - 12. Greenish yellow above, shading to white below, with 5 prominent vertical black bars that narrow toward belly (Ref. 26938 ). A faint sixth bar may be present posteriorly on caudal peduncle; a black spot at upper base of pectoral fin. The adult male becomes dark bluish, the black bars thus less conspicuous on the body
    Biology: Juveniles are common in tide pools while adults found over shallow reef tops. Adults frequently form large feeding aggregations of up to several hundred individuals. Food items include algae, small crustaceans and fish, and various invertebrate larvae (Ref. 3139 ). At Fernando de Noronha Archipelago, this species feeds on spinner dolphins’ feces and vomits. The offal feeding may be regarded as a simple behavioral shift from plankton feeding to drifting offal picking. Also, juveniles may hold cleaning stations together with the doctorfish (Acanthurus chirurgus) and the blue tang (Acanthurus coeruleus) and graze algae as well as pick molted skin and parasites from green turtles (Chelonia mydas ). This behavior is preceded by a characteristic inspection usually followed by feeding nips on the turtles’ skin (head, limbs, and tail), as well as on the carapace. The most inspected and cleaned body parts are the flippers (Ref. 48727, 51385). Adult males adopt a bluish ground color when guarding eggs. Oviparous, distinct pairing during breeding (Ref. 205 ). Eggs are demersal and adhere to the substrate (Ref. 205 ). Attracted to divers who feed fish. Marketed fresh (Ref. 3139 ). Has been reared in captivity (Ref. 35420 ).
