Short description Morfología | Morfometría

Espinas dorsales (total): 11; Radios blandos dorsales (total): 14-15; Espinas anales 3; Radios blandos anales: 14 - 15. This species is distinguished by the following characters: elongate supramaxilla and posterior end of maxilla produced as a thin flexible lamina, in adults it usually extends almost to or beyond rear margin of opercle; dorsal fin with an ocellated spot between third or fourth and eighth spines; inner lining of upper jaw and adjacent membranes with a single conspicuous black stripe that touches ventral margin of maxilla for most of its length; D Xl,14 or 15 (exceptionally 15); body with about 68-95 oblique scale rows; total gill rakers 36-45, usually 39-45 (Ref. 81517).

Inhabits burrows in shallow coastal waters. Also found in sand/rubble bottoms in 2-17 m (Ref 90102).
