Morphology | Morphometrics
Vertebrae: 137 - 145. This species is distinguished by the following characters: tail 1.8-1.9, head 14-19, and body depth 53-67 in total length; preopercular pores 3 and pores in supratemporal canal 3; conical teeth, uniserial on jaws and vomer; vomerine teeth 5-7; body coloration nearly uniform pale yellow to tan, fresh specimens have a fine sprinkling of melanophores which can take on a mottled or freckled appearance; two brown blotches behind the eye surround a pale patch about equal to eye; and MVF 62-142, total vertebrae 137-145 (n=14) (Ref. 101270).
Burrows in the sand on the continental shelf (Ref. 4455).
