Elasmobranchii (haaien en roggen) (sharks and rays) > Rajiformes (Skates and rays) > Rajidae (Skates)
Etymology: Raja: Latin, raja, -ae = a sting ray (Raja sp.) (Ref. 45335); mauritaniensis: Named for the geographic region of the type specimens; i.e. Mauritania, to acknowledge the intent by Capapé (1977) to name this skate based on its known distribution..

Issue
Raja africana Capapé, 1977 is a homonym, being preoccupied by Raja africana Bloch & Schneider, 1801(Ref. 26282) and thus needs a replacement name which is Raja mauritaniensis White & Fricke, 2021 (Ref. 124211).

Estimates based on models

Preferred temperature (Ref. 123201): 13.5 - 17.4, mean 15.1 °C (based on 42 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00269 (0.00124 - 0.00582), b=3.26 (3.09 - 3.43), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
