Elasmobranchii (sharks and rays) > Rajiformes (Skates and rays) > Gurgesiellidae (Pygmy skates)
Etymology: Cruriraja: Latin, crur, cruris = pertaining to a leg + Latin, raja = a ray (Raja sp) (Ref. 45335).
Eponymy: This is named after the Woods Hole Oceanographic Institute research vessel ‘Atlantis’, which collected three new species of skates along the coasts of Cuba, including this one. (Ref. 128868), visit book page.

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

Short description Identification keys | Morphology | Morphometrics

Large width interspace between first and second dorsal fins. Upper surface pale brown disc without definite markings. Lower surface whitish or yellowish. Tail pale dusky below (Ref. 6902).

Deep water species (Ref. 6902). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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. 123201): 7.4 - 13.7, mean 9.5 °C (based on 24 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00661 (0.00222 - 0.01969), b=2.95 (2.71 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±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 (35 of 100).

Price category (Ref. 80766): Medium.
