Longhorn cowfish grow to a maximum size of 45cm. They occur at depths of up to 100m.  Their bodies are enclosed in an “armour” of fused bony scales and they have two prominent horns protruding above their eyes. Longhorn cowfish are commonly found in harbours and estuaries.

Unlike other fish, they do not have gill covers. These fish are known to make grunting noises when they are caught. They are often dried and sold as ornaments.
