Diagnosis: presence of a lozenged melanin pattern; no spots on pectoral fins; no radiating melanin pattern on the head; no highly contrasting, anastomosing horizontal and vertical melanin components on the body; body depth 38.1-40.9% of standard length; head length 32.0-33.8% of standard length; length of lower jaw 36.3-40.8% head length; dorsal fin base 53.3-57.7% of standard length (Ref. 55922).
Found over sandy substrates (Ref. 5595, 55922). Juveniles may be found in shallow water near rocks while adults forage in deeper regions with sandy substrate (Ref. 5595). Feeds on small fish (Ref. 5595, 55922) and invertebrates (Ref. 55922). Half-grown individuals have been observed to remain motionless, partially buried in the sand, waiting for small fishes to come within reach (Ref. 55922).
