Longhorn Cowfish (Lactoria cornuta) - Wiki

Longhorn cowfish
From Wikipedia, the free encyclopedia

[Photo] Several boxfish, including the longhorn cowfish. The 42nd plate from Ernst Haeckel's Kunstformen der Natur (1904), depicting organisms classified as Ostraciontes. Species: Ostracion cornutus = Lactoria cornuta, Ostracion quadricornis = Acanthostracion quadricornis, Ostracion auritus = Aracana aurita, Ostracion turritus = Tetrosomus gibbosus. Classification: Order Tetraodontiformes

The longhorn cowfish, Lactoria cornuta, is a variety of boxfish from the Ostraciidi family, recognisable by its long horns that protrude from the front of its head, rather like those of a cow or bull. They are a resident of the Indo-Pacific region and are usually around 10cm (4ins) long. Whilst badly suited to the home aquarium, the cowfish is becoming increasingly popular as a pet.

Adults are often solitary and territorial, live around sand or rubble bottom up to a depth of 50 m. They are omnivorous, feeding upon benthic algae, various microorganisms, and foraminiferans that it strains from sediments, sponges, polychaete worms from sand flats, mollusks, small crustaceans, and small fishes, able to feed on benthic invertebrates by blowing jets of water into the sandy substrate.

Primary habitat is coral reefs in lagoons, on reef flats, and on protected seaward reefs. Juveniles associate with Acropora corals. Depth range is 3.3???148 ft (1???45 m, perhaps up to 100 m).

Red Sea and East Africa eastward through Indonesia to Marquesas, northward to southern Japan. Including Tuamotus, southern Korea, north to the Ryukyu Islands of southern Japan, south to Australia and Lord Howe Island, and off southern Africa in the Atlantic. Tropical and subtropical waters.

There is no known sexual dimorphism, so both male and female display a yellow to olive base color, which is decorated with white or bluish spots. Paired courtship just before or after sunset. Eggs and larvae are pelagic.

One distinction from other fish is the lack of a gill cover, which is replaced by a small slit or hole. The hexagonal plate-like scales of these fish are fused together into a solid, triangular, box-like carapace, from which the fins and tail protrude. Their unique method of swimming, called ostraciform swimming, causes them to look as if they are hovering. They have no pelvic skeleton, so they lack pelvic fins. They are such slow swimmers cowfish are easily caught by hand, making a grunting noise when captured. This is the most well-known cowfish species in the aquarium trade.

If severely stressed, this species can exude deadly toxin, ostracitoxin, an ichthyotoxic, hemolytic, heat-stable, non-dialyzable, non-protein poison in the mucous secretions of their skin. It is apparently unique among known fish poisons; it is toxic to boxfish and resembles red tide and sea cucumber toxins in general properties.
