Short description Morphology | Morphometrics

Large skate with a moderately long snout, small eyes, and a flat disc; tail about as long as body; small inconspicuous, light thorns on upper surface including snout (Ref. 5578). Medium grey to brownish dorsally, often with dark spots; white or mottled with dusky patches ventrally (Ref. 5578).

Biology     Glossary (e.g. epibenthic)

Found in deeper shelf and slope waters (Ref. 4426). Feed on bottom crustaceans, dragonets, rattails, hake, lanternfish, sea pens, cuttlefish and polychaete worms (Ref. 5578). 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 7.4 cm long and 7.4 cm wide (Ref. 41249). Caught by hake trawlers (Ref. 5578).

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

Oviparous, 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 of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00309 (0.00140 - 0.00684), b=3.20 (3.02 - 3.38), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.9   ±0.63 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100) .
Price category (Ref. 80766):   Medium.
