Short description Chiavi di identificazione | Morfologia | Morfometria

A slim, gray shark with tips of dorsal fins black and edges of pectoral, pelvic and caudal fins white; two dorsal fins each with strong, ungrooved spine at front edge (Ref. 26938).

Inhabits continental shelves and uppermost slopes. Found in 60 to 380 m deep (Ref. 26938). Found on or near the bottom in large, dense schools. Probably feeds on bottom fishes and invertebrates. Ovoviviparous, with about 10 young per litter. A huge parasite (isopod) lives in its buccal cavity. Seldom used for food, but taken in commercial catches for its liver which yields oil and vitamins. Maximum depth reported taken from Ref. 55584.

Estimates based on models

Preferred temperature (Ref. 123201): 13.6 - 23.7, mean 18.7 °C (based on 111 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00339 (0.00162 - 0.00707), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.6 se; based on diet studies.

Resilienza (Ref. 120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Fec=10).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (66 of 100).

Price category (Ref. 80766): Medium.
