Short description Identification keys | Morphology | Morphometrics

Large species of Urotrygon with a round disc; tail short. Dorsal surface of disc and tail yellow-brown or tan irregularly spotted with brown or black blotches; ventral surface of disc white with lateral margins of disc and posterior border of pelvic fins tan in juveniles, dark brown or gray in adults. Small pungent denticles densely cover dorsal surface of disc and tail; denticles only slightly enlarged near midline. Pupillary operculum a small triangle, apex not reaching ventral margin of pupil.

Found in tide pools and to a depth of 85 m. Usually collected in waters shallower than 10 m.

Estimates based on models

Preferred temperature (Ref. 123201): 27.9 - 29.1, mean 28.5 °C (based on 98 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01413 (0.00575 - 0.03468), b=3.07 (2.86 - 3.28), 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 (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (28 of 100).
