Short description Identification keys | Morphology | Morphometrics

Dark brown in color (Ref. 26346). Wing tips rounded; snout shorter than most other skates; skin smooth, soft and loose, with band prickles on hind body and tail (Ref. 26346).

Inhabit the continental slope (Ref. 26346). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 3.7 cm long and 2.2 cm wide (Ref. 41249).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Oviparous (Ref. 26346). Paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).

Estimates based on models

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

Bayesian length-weight: a=0.00550 (0.00273 - 0.01106), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.7 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): Moderate vulnerability (40 of 100).
