Longhorn cowfish (Lactoria cornuta). This fish inhabits reefs in the tropical Indo-Pacific region, from the Red Sea to Micronesia. The long horns make it less appealing to predators. It feeds mainly on invertebrates, which it uncovers from the sand by blowing water onto them. It can reach a length of over 40 centimetres. Photographed off Sulawesi, Indonesia.
