Sohal surgeonfish (Acanthurus sohal) over a coral reef. Behind them is a shoal of sergeant major fish (Abudefduf sp.). The Sohal surgeonfish (or tang) inhabits tropical waters in the Red Sea and Arabian Gulf. Surgeonfish are named due to the presence of a sharp spine at the base of their tail, which is orange in this species. This is used to deter predators. The Sohal surgeonfish may reach a length of around 40 centimetres. It is a popular aquarium fish as it is beautiful and hardy. Photographed in the Egyptian Red Sea.
