Batfish, any of about 60 species of fishes of the family Ogcocephalidae(order Lophiiformes), found in warm and temperate seas. Batfishes have broad, flat heads and slim bodies and are covered with hard lumps and spines. Some species have an elongated, upturned snout. Batfishes grow at most about 36 cm(14 inches) long. They are poor swimmers and usually walk on the bottom on thickened, limb-like pectoral and pelvic fins. Most live in the deep sea, but some inhabit shallow water. 1, record 1, English, - batfish

Hard rock from the sea floor is difficult to recover. The customary method is to tow a dredge, a heavy iron box or pipe, along the bottom in hope of breaking off fragments(...) One end of the dredge is closed with chain mesh or an iron grill to trap solid fragments while permitting water and soft sediment to wash through; the other is open, attached by a chain bridle to a cable from the ship. 2, record 3, English, - geological%20dredge
