Description synthétique Clés d'identification | Morphologie | Morphométrie

Lower surface of the discus dark brown, darker in upper surface. Without definite markings, outer edges of pectoral and pelvic fins shading to darker (Ref. 6902).

Found on deeper continental slopes and probably abyssal plains, mainly deeper than 1,400 m (Ref. 3167). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). It is caught as by-catch in low numbers by deep trawl fisheries (Ref. 117245).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves

Oviparous (Ref. 3167). Paired eggs are laid. Embryos feed solely on yolk (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 115969): 3.4 - 6.6, mean 5.4 (based on 13 cells).

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

Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.45 se; based on food items.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100).

Rajella bathyphila (Holt & Byrne, 1908)
