The preopercle is rounded and has a shallow incision, with the serrations on the margin below the incision enlarged. The gill cover has a straight upper margin. The dorsal fin contains 11 spines and 14-16 soft rays and the

Habitat and biology

''Epinephelus spilotoceps'' occurs in shallow coral reefs, mainly in patch reefs within lagoons, the upper slopes of channels through reefs and the outer reef margins. It has been recorded on rubble patches in the Maldives, mostly close to the edges and in the vicinity of the more complex coral formations and avoiding being out in the open. In captivity they feed on crustaceans and fish.
