Short description Chiavi di identificazione | Morfologia | Morfometria

This species is distinguished from its congeners in Bathyraja in having a whitish area along the inner margin of eyes; dorsal side of disc with minute fine prickles; pointed clasper with a pseudosiphon-like groove; dense, minute prickles covering smaller egg capsule (Ref. 75535).

Juveniles feed mainly on amphipods, adults feed on crabs and fish (Ref. 27640). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 7.6 cm long and 5.5 cm wide (Ref. 41249).

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs have horn-like projections on the shell (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 0.8 - 3.6, mean 1.8 (based on 126 cells).

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

Bayesian length-weight: a=0.00468 (0.00303 - 0.00721), b=3.05 (2.92 - 3.18), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.66 se; based on food items.

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (53 of 100).
