Description synthétique Clés d'identification | Morphologie | Morphométrie

This species is distinguished by the following set of characters: disc large, width at anterior orbit 8.0-9.1 times mouth width; tail short, postcloacal length 35-42% of disc length; eyes relatively small, orbit diameter 10.9-15.7 in horizontal snout and 13.1-17.9 in head lengths respectively; distal portion of tail weakly or slightly expanded, width of tail near tip 1.5-1.6 times tail width at its midlength; pectoral-fin radials 72-76; moderate-sized pelvic fins, anterior lobe 15.4-16.0% TL; anterior pelvic-fin lobe rather broad-based, width 1.7-2.2 in distance between pelvic-fin origins; caudal fin rudimentary; tooth rows in each jaw of adults 24-30; monospondylous vertebral centra 26-29, total centra 184-212; dorsal and ventral surfaces bluish in fresh specimens (Ref. 75174)..

Found on upper continental slope. Life history unknown but presumably feeds on invertebrates and bony fishes (Ref. 114953).

Estimates based on models

Preferred temperature (Ref. 123201): 4.7 - 5.6, mean 5.1 °C (based on 9 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).

Niveau trophique (Ref. 69278): 3.8 ±0.7 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100).
