Short description Morphology | Morphometrics

Dorsal spines (total): 1; Anal spines: 0; Anal soft rays: 0. This species is distinguished by the following characters: long, pointed, narrow, depressed snout; relatively large eyes (EYL 7.2-9.0% BDL) and virtually above the mouth (Ref. 97389); knobby tooth plates; a rather long first dorsal fin and spine (spine longer than height of first dorsal fin, DSA 1.3-1.4 times in D1H, Ref. 97389); caudal-fin axis weakly raised with the fin asymmetrical, epaxial caudal-fin lobe narrower than hypaxial lobe (Ref. 97389); upper edge of caudal fin without denticles or tubercles. caudal fin lanceolate with no tubercles on upper edge but with a long terminal filament (Ref. 5578, 6871, 41248).

Biology     Glossary (e.g. epibenthic)

Found on the continental slope and ocean floor (Ref. 26346). Appears to feed mainly on shellfish and crustaceans (Ref. 6871). Maximum length 120 cm without tail filament (Ref. 26346).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Estimates based on models

Preferred temperature (Ref. 115969): 0.3 - 9, mean 5.2 °C (based on 654 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7539   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00245 (0.00098 - 0.00614), b=3.14 (2.91 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.50 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Assuming Fec <100).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (47 of 100) .
