Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 0; Espinas anales: 0. Diagnostic features include the very short abdomen, with interspace between pectoral and pelvic fins base shorter than 3/5 of anal fin base length; pectoral fin tip reaching beyond the midpoint between pectoral and pelvic fins; first dorsal fin smaller in area than the second dorsal; posterior end base (axil) of second dorsal clearly in front of anal fin axil; low anal fin with a long base. Egg capsule very slender; without tendrils, conical posterior end. Claspers without hooks, with posterior margin of exorhipidion forming a free lobe (Ref. 37959). Black, brown or grey (Ref. 11146), without conspicuous markings on fins (Ref. 244).

Found on the continental slopes. Poorly known. Oviparous, probably one egg per oviduct laid at a time. Not utilized at present.

Estimates based on models

Preferred temperature (Ref. 115969): 3 - 10.1, mean 3.4 (based on 121 cells).

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

Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 4.0 ±0.4 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Muy bajo, población duplicada en un tiempo mínimo superior a 14 años (Fec assumed to be <10).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).
