Elasmobranchii (sharks and rays) > Rajiformes (Skates and rays) > Rajidae (Skates)
Etymology: Breviraja: Latin, brevis = short, brief + Latin raja = ray (Raja sp.) (Ref. 45335); nigriventralis: From the latin 'nigr' meaning black and 'ventralis' pertaining to the belly (Ref. 31371).

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

Maturity: L_m ? range ? - ? cm
Max length : 40.0 cm TL male/unsexed; (Ref. 31371)

Estimates based on models

Preferred temperature (Ref. 123201): 5.7 - 6.8, mean 6 °C (based on 4 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [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).

Trophic level (Ref. 69278): 3.7 ±0.6 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): Low to moderate vulnerability (30 of 100).
