背面の脊椎 (合計) : 12 - 14; 背鰭 (合計) : 11 - 14; 肛門の骨: 3; 臀鰭: 7 - 9; 脊つい: 30 - 32. Body slightly elongated, highest at origin of dorsal fin; dorsal profile gently rounded, ventral profile rather straight (Ref. 35977). Mouth very low; jaws usually equal; maxillary may or may not extend to a vertical line through anterior margin of eye (Ref. 35977). All teeth on both jaws conical, recurved, arranged in outer and inner series (Ref. 35977). First dorsal spine very short, all spines with a lappet near tip; all dorsal fin soft rays usually branched (Ref. 35977). First anal spine very short, length of subsequent spines increasing progressively, and all spines with a small lappet near tip (Ref. 35977). Pectoral fin reaching between anus and third anal fin spine (Ref. 35977). Pelvic fin filamentous, reaching between anus and second anal fin spine (Ref. 35977). Scales ctenoid on lateral surface of body (Ref. 35977).
Body shape (shape guide): fusiform / normal.
Occurs over sand bottoms near rocks where they feed on invertebrates. Forms schools. Bury themselves in the sand to evade predators (Ref. 6770).
