This species is distinguished by the following characters: D XII,7-9 with the last divided at base; pectoral fin rays 16-18, uppermost branched pectoral fin ray is usually the third (rarely second to fourth); lacrimal usually with 2 spines over maxilla that point at nearly right angle from each other, posterior pointing ventrally and slightly anteriorly; occipital pit is well-developed; anteriormost mandibular lateral line pores are widely separated; scales small, emarginate, no distinct ctenii; scale rows in longitudinal series 56-60; no scales on chest and pectoral fin base; cirri well developed over entire head and body, no cirri on lower jaw (Ref. 122805).
Solitary and sedentary. Common among rocks and algae. Feeds on small fishes (gobies, blennies), crustaceans and other invertebrates (Ref. 4570).
