Short description
Identification keys | Morphology | Morphometrics
This species is distinguished by the following characters: wedge-shaped disc, its dorsal surface scaled but no thorns; snout length 2.5-2.6 times interspiracular distance; orbit moderately large, diameter 1.6-1.9 times spiracle length; nostrils oblique, length 1.4-1.6 times internarial distance; anterior nasal-flaps inserted well into internarial space, but never almost united near ventral midline; posterior nasal flaps broad; ridges of rostral cartilage well-separated dorsally and almost parallel; prebranchial sensory-pore patch narrow, extending to first gill slit; distance between first gill slits 1.3-1.4 times distance between fifth gill slits; distance between fifth gill slits 2.5-2.9 times in ventral head length; postscapular sensory canal long, not grooved, extending more than three-quarters distance to pectoral-fin insertions; moderately tall dorsal-fins; pelvic-fin inner margin distinctly longer than its base in mature males, shorter than base in females; interdorsal distance more than 2.5 times first dorsal-fin base; outer spiracular fold distinctly larger than inner fold; dorsal margin of caudal fin about 2.0-2.2 times preventral margin; 162-171 post-synarcual vertebral centra; about 50 nasal lamellae; dorsal disc plain brownish or with faint dusky blotches or fine dark spots (Ref. 58070).
This species is mostly collected at depths shallower than 150 m. Male individuals mature at 46 cm TL, immature at 37.6 cm TL (Ref. 58070).
