Head pointed. Mouth oblique; large for the genus, maxillary nearly reaching a vertical at front edge of orbit. Gill rakers short, the longest on first gill arch about 1/3 length of longest gill filaments. Thoracic scales about half height of those on the side of the body, becoming smaller ventroanteriorly. Small scales on nape extending forward nearly to a vertical at rear edge of orbit. Dorsal spine progressively longer; caudal fin rounded; first pelvic fin ray elongate, especially in large males (Ref. 12420). |
