Short description Morphology | Morphometrics

A dwarf softnose skate with a bluntly pointed snout and very large close-set eyes; tail longer than body in adult; pectoral disc angular with rounded corners, and anterior edges more undulated in adult male than in female; large thorns around eyes, on shoulders, and in interrupted single row from back to dorsal fins (Ref. 5578). Brownish-grey above, with 6-7 crossbars on tail; underside pale with dark brown areas along the front and rear edges of disc, on snout and on underside of tail (Ref. 5578).

Biology     Glossary (e.g. epibenthic)

Found on the upper slope (Ref. 5578). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Probably taken 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).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5312   [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):  3.7   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (30 of 100) .
