Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm SL male/unsexed; (Ref. 9774); common length : 12.5 cm SL male/unsexed; (Ref. 9774)
soft rays: 52 - 55;
Vertebrae: 33 - 35. Body uniformly brownish, 2 ocelli above and below lateral line and 1 ocellus on posterior third of straight section of lateral line. Many indistinct rings scattered on body and median fins. Teeth in upper jaw small and close-set with3 or 4 pairs of canines anteriorly, teeth in lower jaw stronger and more widely spaced than those in upper jaw. Gill rakers pointed and rather short. Pectoral fin on ocular side with 12-13 rays (Ref 9774).
Inhabits deep waters on mud and sand bottoms of the continental shelf (Ref. 9774). Feeds on benthic animals (Ref. 4896). Marketed fresh and salt-dried (Ref. 9774).
