Indian Sailfin Tang
Zebrasoma desjardini
With its small, protruding mouth and sharp teeth, the Indian Sailfin Tang grazes on algae growing on hard substrates, helping to prevent algae from overgrowing the corals.
A characteristic feature of this species are the sharp, spine-like horny plates at the base of the tail, also known as “scalpels.” The Indian Sailfin Tang uses these to defend itself against predators and conspecifics. The sheaths of these spines are strikingly black. To intimidate others, the fish erect their large dorsal and anal fins, making them appear larger.
Males and females look very similar. However, males usually grow slightly larger and display more vivid colors during the breeding season. In particular, the light and dark stripes on the head become more prominent at that time.
