The members of the family Chaetodontidae, popularly know as butterflyfishes, coralfishes and bannerfishes. Most species of butterflyfish live in the warm tropical seas of the Indo-Pacific (about 90%) with the remainder in the Atlantic. Only a few species are found in subtropical waters, bordering onto subtemperate zones. The butterflyfish have a highly compressed body in which the back is raised , forming an elongate-oval to near circular shape in some; a small protactible mouth with brush-like teeth in the jaws; a continuous dorsal fin with strong and sharp spines in the anterior section, followed by a large-surface soft part; an anal fin mirroring the soft part of the dorsal fin , headed by 3-5 strong spines, of which the 2nd is often greatly enlarged.
Widespread between Venezuela and Florida. Commonly observed in the Caribbean region. Occurs on various reef habitats , often wandering over adjacent weed areas, to about 20m depth. Adults form pairs, whilst juveniles are solitary. Readily identified by the large, whit edged black ocellus at the end of the dorsal fin base. Very small juveniles feature a second ocellus, slightly smaller, just above. Length to 14cm.
