To about 50 cm. Deep, compressed and oval, red to silvery with reddish barring, an upturned mouth with a projecting lower jaw, a very large eye and a dark blotch at the base of the pelvic fin.

The glasseye snapper is the pair to separate it from and the tail does it: slightly concave here, rounded there. This fish also lacks the oval dark specks that the glasseye carries on its soft dorsal, anal and tail fins.

Ten to two hundred metres, usually fifteen to a hundred, over coral reef and rocky bottom. It is nocturnal, forming small groups near the bottom by day and feeding at night on small fish, crustaceans and worms.

Ciguatera is reported.
