Epinephelus tauvina grows up to 75 cm (30 inches) in length.
 These fish have a wide, upward-facing mouth with rather thick lips.
Their heads and bodies are pale greenish grey or brown with round spots, varying from orange-red to dark brown.
A group of black spots may be visible on the body at the base of the rear of the dorsal fin.
Five vertical darker shaded bars may also be present on their bodies.

It is similar to  E. corallicola and E. howlandi, which, however, have shorter bodies and spots less closely spaced.

Due to confusion about identifying species, much of the earlier (particularly before 1984) literature referring to E. tauvina may actually refer to other species of grouper, including Epinephelus coioides, Epinephelus malabaricus and Epinephelus lanceolatus.
