Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 2; Rückenflossenweichstrahlen (insgesamt): 122; Afterflossenstacheln 0; Afterflossenweichstrahlen: 94. Head large, scaled completely except for a narrow ventrolateral strip on snout; eyes also large; snout short, pointed and with tubercular scales along its leading edge; chin with a small chin barbel. Body tapering to a point posteriorly from behind the insertion of the first dorsal-fin spine. Scales adherent, with 3 to 5 divergent rows of coarse spinules. Pyloric caeca 12 to 14. Overall color is gray to grayish-brown in young, turning to dark brown in adults; fins generally dark. Branchiostegal rays: 6-6 (Ref. 36385).

A benthopelagic mid-slope species, that appears to wander off slope bottoms into midwater (Ref. 1371). Adults feed on small fish, euphausiids, prawns, amphipods and cephalopods (Ref. 1371). Oviparous, with planktonic larvae (Ref. 36385).

Estimates based on models

Preferred temperature (Ref. 115969): 2.3 - 3.8, mean 2.4 (based on 174 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00141 (0.00085 - 0.00234), b=3.19 (3.04 - 3.34), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.54 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (K=0.02-0.04; tmax=73).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (79 of 100).

Preiskategorie (Ref. 80766): Medium.
