简单描述
检索表 | 型态特徵 | 形态测量图
This species is distinguished by the following combination of characters: moderate-sized disc, its width at anterior orbit 5.2-7.8 times mouth width; moderately elongate to short tail, its postcloacal length 79-170% of disc length; relatively large eyes with orbit diameter 4.7-8.8 in horizontal snout and 6.7-10.6 in head lengths, respectively; distal portion of tail expanded laterally in specimens exceeding about 28 cm TL (130 mm DW), width of tail near tip 1.3-2.2 times tail width at its midlength; pectoral-fin radials 66-71; moderate-sized pelvic fins, anterior lobe 12.1-18.1% TL; anterior pelvic-fin lobe rather broad-based, width 1.7-3.2 in distance between pelvic-fin origins; caudal fin rudimentary; tooth rows 20-28, in each jaw of adults; with teeth of adult males with greatly elongated conical cusps; 25-31 abdominal vertebral centra; 148-171 total centra; dorsal surface pale pinkish brown, ventral surface uniformly pale (Ref. 75174).
Body shape (shape guide): other.
Found on outer continental shelf and upper slope. Presumably feeds on small fishes and invertebrates. Males reaches maturity at ca. 43 cm TL; smallest neonatal juvenile 13 cm TL (Ref. 114953)
