Morphology | Morphometrics
soft rays: 10;
Vertebrae: 27 - 28. Body densely covered with modified scales which form spinous points; depth less than 1/3 SL.. Lachrymal with 3 strong sharp spines, the first of moderate size , points mostly forward, continuous with ridge at base of larger 2nd spine (about equal in length to 3rd), directed downward, slightly curved; 3rd spine points mostly back. Second infraorbital bone with 2 spines, 1 above other, with obscure circular lateral line pore. Interorbit with nearly parallel ridges, stronger posteriorly (Ref. 35984, 39602).
Occurs on soft bottom. Benthic (Ref. 75154).
