Short description Identification keys | Morphology | Morphometrics

Subtrapezoidal disc, a uniform purplish-brown, brown, or tan dorsal coloration (devoid of any other markings), and wide, broadly rounded tooth bands (Ref. 49866).

Found in continental waters, both inshore and offshore (Ref. 9912). Occurs over soft bottoms; feeds on bottom-living organisms; possesses electric organs (Ref. 68964). Biology little known (Ref. 9912). Gravid females produces 2-3 pups during each gestation. Males mature at ca. 14 cm TL; born at ca. 6 cm TL (Ref. 114953).

Estimates based on models

Preferred temperature (Ref. 123201): 21.9 - 28.6, mean 27.1 °C (based on 1313 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01175 (0.00476 - 0.02897), b=2.88 (2.66 - 3.10), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.3 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).

Price category (Ref. 80766): Unknown.
