Characteristics

The fishes in the genus ''Mycteroperca'' have oblong bodies in which the depth of the body is less than the length of the head, which is a quarter to just under a third of the standard length. The length of the snout is noticeably longer than the diameter of the eye. The dorsal profile of the head is convex and the area between the eyes is also convex, having a width greater than the diameter of the eyes (in fish with a standard length greater than ). The edges of the preopercle are serrated and the serrations at the bones angle may, or may not, be enlarged. The upper edge of gill cover is convex. The lower edge of upper jaw is straight near the joint and there is no knob, distinct step or hook present. The supramaxilla well developed. The lower jaw projects beyond the upper jaw and there are obvious canines in the front of both jaws while there are also teeth on roof of the mouth. In these fishes the
