Other fresh-water fishes on this floor are the small lad-der fish, a rare little fish from the interior rivers of SouthAmerica, common catfish, chub, sucker, red horse, Missis-sippi catfish and spotted catfish, sunfish, fresh-water killie,white perch and the burbot, a fresh-water representative ofthe cod family. A tank of very interesting little sea horses, the only fishwith a prehensile tail, is also exhibited on this floor. Thesea horses are difficult to keep in captivity because theyfeed only on the minute crustaceans infesting the eel grassin which they live. The male of this species hatches theeggs and cares for the young in an abdominal pouch. En-closed in a skeleton of horny segments that permits littlelateral flexion, and having only one dorsal fin, the sea horse 142. SEA HURsl s MUD PUPPY THE NEW YORK AQUARIUM is a poor swimmer and cannot resist currents, remainingfor the most part stationary, attached by its tail to grassesor seaweeds. Its comparatively large air bladder is an im-portant factor in its equilibrium. If this is pricked to letout a bubble of gas the size of a small pinhead, the fish fallsto the bottom, where it must remain until the wound ishealed and a new supply of gas secreted to enable it torise.
