Facts about this animal
The horned boxfish is one of the larger trunkfish, reaching a length of over 45 cm. As its name implies, it has very long horns on the forehead. It also hs a long tail which increases proportionally with age.
The horned boxfish has no dorsal or anal spines but 8-9 dorsal and 8-9 anal soft rays, pectoral fins with 10-11, and caudal fin with 9-10 soft rays. The colour ranges from green and olive to orange with blue spots.
Cowfish are slow swimmers. Their rigid body is propelled primarily by the large, undulating dorsal fin, and the two pectoral fins. The tail and tail fin are used for steering. Like a helicopter, they are able to swim backwards.
Adult longhorns are solitary, juveniles often form small groups, which may be found on protected shallow mudflats.
Adult and juvenile horned boxfish feed on benthic invertebrates, mainly custaceans, by blowing away the sand. Wrasse often follow them around, looking for an easy meal. Tuna fish predate on long-horned boxfish.
Did you know?
that cowfish have a hard carapace that acts as both a skeleton and armour? When threatened, they also can release toxin to ward off potential predators. This "ostracitoxin" is exuded through the skin from almost all areas of the body, but primarily from the flanks or sides.

Why do zoos keep this animal
Horned boxfish are not an endangered species but their habitats, coral reefs, are threatened in many places. They are thus presented by zoos and aquariums as an ambassador species for reef protection.
