Short description Claves de identificación | Morfología | Morfometría

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).

A rare species known only from 2 specimens both of which are missing (Ref. 2708). Oviparous (Ref. 50449).

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=0.00661 (0.00222 - 0.01969), b=2.95 (2.71 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.7 ±0.5 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).
