Descrição breve Chaves de identificação | Morfologia | Morfometria

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).

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)

Estimates based on models

Preferred temperature (Ref. 115969): 7.8 - 14.6, mean 11.1 (based on 40 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).
