Juvenile blacksaddle filefish (Paraluteres prionurus) mimicking a black-saddled toby (puffer) fish (Canthigaster valentini) beside hard coral. This fish is found throughout the Indo-Pacific. It mimics the poisonous black-saddled puffer fish to confuse potential predators, however it is actually harmless. Photographed off Sangalaki Island, in the Sulawesi Sea, Indonesia.
