Description

The longnose batfish is a bizarre bottom fish of the family Ogcocephalidae from the western Atlantic around Brazil. The species has a strongly flattened, triangular body covered with bumps, a prominent snout and arm-like pectoral and pelvic fins with which it 'walks' over the bottom rather than swimming. Between the eyes it carries a small, protrusible lure to attract prey. The fish lives on sand and rock bottoms to about 70 m deep and feeds on small fishes, crustaceans and worms. In Ceará, Brazil it is traded as an aquarium fish. It is harmless to humans.
