Polka-dot Batfish Ogcocephalus radiatus
Fish of the family Ogcocephalidae, to which the polka-dot batfish belongs, are among the most oddly shaped of the anglerfish. They prop themselves up on paired pectoral and pelvic fins that enable them to walk over the sea-bed in search of worms, crustaceans, and fish. Although the polka-dot batfish has a fishing lure, this is very short and evidence suggests it may secrete an odor that attracts potential prey. A hard, spiny skin protects these fish from predators, but they are so sluggish that divers can pick them up.
