Description
The polka-dot batfish is a remarkable bottom fish of the batfish family (Ogcocephalidae) from the western Atlantic. The species grows to about 38 cm and has a strongly flattened, nearly round body with arm-like pectoral and pelvic fins with which it 'walks' over the bottom rather than swimming; the body bears conspicuous dark spots. Beneath the snout is a small, retractable lure to attract prey. It occurs from the water's edge to 70 metres. As a slow bottom hunter it feeds on small crustaceans, molluscs, worms and small fishes. The species is harmless to humans.
