This species is defined by the following set of adult characters: disc wedge-shaped, width 32-33% TL, length more than 1.3 (1.35-1.39) times width; snout moderately elongate, length 3.4-3.6 times interspiracular distance, 5-5.5 times interorbital width; orbit medium-sized, 1.5-1.6 times spiracle length; nostrils weakly oblique, length 1.3-1.4 times internarial distance; preoral length 7.7-8.1 times internarial distance; anterior nasal flaps penetrating slightly into internarial space, however, well separated at their insertion; posterior nasal flaps broad; spiracular folds 2, outermost fold only slightly taller than inner fold; ridges of rostral cartilage almost parallel, converging slightly anteriorly but not constricted medially; anterior cartilage sickle shaped, pointed posteriorly; distance between fifth gill slits 3.1-3.4 times in ventral head length; prebranchial sensory pore patch obvious, extending to first gill slit; postscapular sensory canal obscure, without exposed lateral pores, not grooved; thorn patches on supraorbit, scapular region, and dorsal midline rudimentary, inconspicuous; inner margin of pelvic-fin slightly shorter than its base; interdorsal distance more than 2.5 (2.8-3.1) times first dorsal-fin base; dorsal caudal margin about 2.1 times preventral margin; upper jaw with 62-77 tooth rows; post-synarcual centra 176-180; nasal lamellae more than 50 (51-55); dorsal fin not distinctly bicolored; white spots absent on dorsal disc (Ref. 72461).
Body shape (shape guide): elongated.
Body shape (shape guide): elongated.
Demersal inshore on inner insular shelf. Mainly feeds on small crustaceans (Ref. 114953). The smallest pregnant female observed from this species was 74.7 cm TL; with pregnant females having 6-11 embryos, birth size unknown, but embryos well developed at 13 cm TL (Ref. 72461). Males mature at 77-80 cm TL. Females produces litters of 6-11 pups (Ref. 114953).
