Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. Caudal fin without a rippled dorsal margin and ventral lobe but with a strong subterminal notch; vertebral axis of caudal fin little raised above body axis (Ref. 13566). Round dark brown spots and indistinct saddles (Ref. 13566).

A little-known, uncommon bottom-dwelling shark found on the shelves of continental and insular waters (Ref. 244). Dwell on the sublittoral zone, 50-320 m (Ref. 11230). Food habits little known; probably feeding on bony fishes, crustaceans and cephalopods (Ref. 244). Oviparous (Ref. 50449), with 1 to 2 pups in a litter (Ref. 244).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.6328 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic Level (Ref. 69278): 4.1 ±0.57 se; Based on food items.

Resilience (Ref. 69278): Very Low, minimum population doubling time more than 14 years (Fec = 1-2).

Vulnerability (Ref. 59153): Low to moderate vulnerability (29 of 100) .

Price category (Ref. 80766): Unknown.
