Short description Morphology | Morphometrics

A legskate with a pointed thornless snout and with large whitish thorns on shoulders, around the eyes, and in a single row from the nape to the 1st dorsal fin (Ref. 5578). Legskates have pelvic fins separated into a mobile leg-like front lobe, and a rear lobe that may be fused to the tail base (Ref. 5578). Uniformly reddish-brown above, lighter below (Ref. 5578).

Biology     Glossary (e.g. epibenthic)

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5039   [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):  3.6   ±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 (28 of 100) .
