Elasmobranchii (sharks and rays) > Rajiformes (Skates and rays) > Arhynchobatidae (Softnose skates)
Etymology: Bathyraja: Greek, bathys = deep + Latin, raja, -ae = a ray (Raja sp) (Ref. 45335).

Environment: milieu / climate zone / depth range / distribution range Ecology

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Southern Ocean: Orkney and South Shetland islands to the Antarctic Peninsula. Probably more widespread in continental waters into the Weddell Sea and eastward as well as into the Pacific Ocean sector westward. Southeast Pacific: Chile (Ref. 9068).

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 120 cm TL male/unsexed; (Ref. )

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 15.66 cm long and 8.0 cm wide (Ref. 41249). Regularly taken as bycatch in trawl hauls and may be used as fishmeal. Minimum depth from Ref. 58018.

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

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).

Estimates based on models

Preferred temperature (Ref. 115969): -1.4 - 1.2, mean -0.2 (based on 89 cells).

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

Bayesian length-weight: a=0.00525 (0.00319 - 0.00862), b=3.12 (2.98 - 3.26), in cm Total Length, based on LWR estimates for this species & 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 to very high vulnerability (72 of 100).

Climate Vulnerability (Ref. 125649): Very high vulnerability (90 of 100).

Price category (Ref. 80766): Medium.
