Description

The roundel batfish is a bottom fish of the batfish family (Ogcocephalidae) from the eastern Pacific. The species grows to about 15 cm and has a strongly flattened, triangular body with arm-like pectoral and pelvic fins with which it 'walks' over the sand bottom rather than swimming; on the back it bears conspicuous round, eyespot-like markings. Beneath the snout is a small, retractable lure to attract prey. As a slow bottom hunter it feeds on small crustaceans and small fishes. Owing to its camouflaged, slow-moving habits it is little noticed. The species is harmless to humans.
