Habitat
Reefs and adjacent sand and rubble

The clown coris is a large wrasse famous for changing utterly as it grows. Juveniles are pale and vividly marked, while adults become dark and heavy-bodied, and dominant males develop a bulging forehead and sombre colouring quite unlike their youthful selves.

A reef-associated fish of the Indo-Pacific, it uses strong canine teeth to crush hard-shelled prey such as molluscs and crustaceans dug from sand and rubble around the reef.
