Total gill rakers 26 to 28. Dorsal fin with X spines and 16 to 18 rays, the third spine longest and the membranes moderately incised between the spines; anal fin with III spines and 8 rays; pectoral fins with 19 or 20 rays; pelvic fins distinctly shorter than pectoral fins and their origin below or behind lower end of pectoral-fin base; caudal fin rounded. Midlateral-body scales ctenoid, with numerous auxiliary scales; lateral-line scales 53 to 69; lateral-scale series 96 to 112.

Distribution

Eastern Pacific from southern California to Peru and the Galapagos Islands. The spotted grouper is the most abundant small grouper in the northern Gulf of California.

Ecology

This species is abundant on offshore patch reefs where it is readily caught by anglers. It feeds mainly on crustaceans and fishes on rocky and sandy bottoms; in winter it moves closer to shore where it feeds heavily on swarms of the pelagic red crab, Pleuroncodes planipes.

Size

Maximum total length about 75 cm; maximum weight probably around 9 kg.
