Description

The Atlantic batfish is a strongly flattened deep-sea anglerfish of the family Ogcocephalidae (batfishes) reaching about 39 cm. The round, armoured body has a rough skin with bony knobs and limb-like pectoral and pelvic fins, with which the fish slowly 'walks' over the bottom rather than swimming. Beneath the short snout sits a small, retractable lure (a remnant of the rod of related anglerfishes). The species lives on soft bottoms of the deeper continental slope of the Atlantic. On the bottom it slowly searches for small crustaceans, worms and molluscs. Because of its bizarre shape and deep lifestyle it is only rarely seen.
