Issue
The large sequence divergences among B. eatonii from the Kerguelen Plateau and from the South Atlantic-Ross Sea provide evidence for two species in these regions. The species, referred to as Bathyraja sp. (cf. eatonii) from the Antarctic continental shelf and slope is a species distinct from B. eatonii. from the Kerguelen Plateau (the type locality) and thus is a new and undescribed species until it is formally described and named (Ref. 93260).

Southern Ocean: common on the Kerguelen Plateau, around South Orkney and South Shetland islands. In the Antarctic Peninsula, it occurs in the northeastern Weddell Sea and on Gunnerus Ridge. A single record comes from the Pacific Ocean sector, in the Ross Sea. Southeast Pacific: Chile (Ref. 9068).

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Estimates based on models
Preferred temperature (Ref. 115969): -1.8 - 2, mean -0.9 (based on 119 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00291 - 0.01038), b=3.13 (2.97 - 3.29), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 4.0 ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153): High vulnerability (60 of 100).
Climate Vulnerability (Ref. 125649): High to very high vulnerability (71 of 100).
