Description
The blacksaddle filefish is a filefish (Monacanthidae) from the Indo-West Pacific. The species grows to about 11 cm and has a white body with yellow-brown and black saddle markings. Remarkably, it mimics the colour and shape of the toxic sharpnose puffer Canthigaster valentini, a form of mimicry that deters predators; it is not itself toxic and has no venom. As a reef-dweller it eats weed, small invertebrates and coral polyps. The fish is harmless to humans.
