Interesting Facts

The Longhorn Cowfish (Lactoria cornuta), also called the Horned Boxfish, is easily recognised by the two long horns on its head and it’s bright yellow body.

The eyes of the Longhorn Cowfish move independently from each other, so these animals are able to look in two different directions at the same time.

This slow-moving and generally peaceful species has poisonous skin and if threatened or stressed they can release a toxin into the water that may be lethal to other boxfish and various other organisms.


Interestingly, the cowfish does not have an internal skeleton like other bony fish, but rather a rigid, hard carapace of fused scales from which the horns, fins, eyes, and lips protrude. This hard, shell-like body looks more like the exoskeleton of crustaceans and similarly functions as protection against predators.
