Morphology | Morphometrics
soft rays: 46 - 53;
Vertebrae: 40 - 43. The species is characterized by the following: vertebrae 11-14 + 27-31 = 40-43, dorsal fin rays 67-77, anal fin rays 46-53; no scales on the head and body; posterior nostril large, about half size of eye; lower preopercular pore large, about size of posterior nostril or larger; weak spine on maxilla positioned behind rear tip of eye; single pair of pseudoclaspers curved, expanded and paddle-like, longer than penis, without fleshy appendices; otolith with pointed posterior tip and concavity above and massive postdorsal angle, otolith length to height ratio 1.9-2.0, sulcus with divided colliculi (Ref. 57886).
Occurs along rocky shores at shallow depths. A female specimen (AMS 15330-037, 42 mm SL), contained 3 embryos, 11-16 mm SL. The species is pale except for some weak pigmentation on top of head (Ref. 57886).
