Élasmobranches (requins et raies) (sharks and rays) > Rajiformes (Skates and rays) > Rajidae (Skates)
Etymology: Caliraja: The prefix name Cali- refers to the state of California, United States and Gulf of California, Baja California, Mexico, the regions where the types of all four recognized species were described.
Eponymy: The etymologies do not help, but we believe these species are named after the Sea of Cortez where the holotypes were caught, or in the case of the eelpout, Cortez Bank off San Diego, California. (Ref. 128868), visit book page.

Estimates based on models

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).

Niveau trophique (Ref. 69278): 3.7 ±0.6 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (29 of 100).
