Distinguished by the following characteristics: buff or greyish brown head and body, whitish ventrally; yellow margins of dorsal and pectoral fins, sometimes including anal and caudal fins; pale blue line from the eye to the angle of preopercle; depth of body less than head length, contained 2.7-2.9 times in SL; head length 2.4-2.6 times in SL; convex interorbital area; angular preopercle, serrae at the angle distinctly enlarged; eye diameter equal to or greater than interorbital width in fish less than 45 cm SL; posterior and anterior nostrils subequal in size (Ref. 89707).
A solitary species (Ref. 26340) occurring in rocky areas and on sand mud bottom. On soft bottoms they are often seen in or near trenches or burrow-like excavations. Feeds on a wide variety of invertebrates (mainly brachyuran crabs) and fishes. Marketed fresh and considered good quality.
