White-spotted Boxfish Ostracion meleagris

The White-spotted Boxfish, also called just the Spotted or Black Boxfish, is native to reefs of the Indo-Pacific Oceans. The fancy colouring of the male is shown above. Females are plain black with white spots (like a boxy Guineafowl Puffer). They reach 25cm long and secrete a toxic mucus coating to deter predators.
