Dorsale stekels (totaal) : 0; Anale stekels: 0. Numerous dark spots on lower lobe of caudal fin (Ref. 31369). Pectoral fins greatly enlarged, with broad triangular lobe extending forward from their bases on either side of the gill slits; pelvic fins enlarged and wing-like; caudal very short, nearly symmetrical but not lunate, its lower lobe slightly longer than the upper (Ref. 31369).

A common but little-known angelshark found on the continental shelf and uppermost slope, on or near the bottom (Ref. 247, 75154). Occurs from close inshore to 130 m depth (Ref. 31369, 6871). Feeds mainly on small fishes and crustaceans (Ref. 6871). Ovoviviparous (Ref. 247). Flesh is highly esteemed (Ref. 6871).

Estimates based on models

Preferred temperature (Ref. 123201): 14 - 20.4, mean 16 °C (based on 129 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00295 - 0.01551), b=3.07 (2.88 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 4.0 ±0.66 se; based on food items.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Prijsklasse (Ref. 80766): Medium.
