The sohal surgeonfish or sohal tang, Acanthurus sohal is compressed laterally, making it extremely maneuverable and fast along the reef. It has a horizontal, blade-like spine along the base of the tail on both sides, which folds into the fish, pointing anteriorly towards the head. During defense and aggression, tangs flick the spine at other fish or intruders, causing physical harm.
