Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 0; Afterflossenstacheln: 0. A large, fairly stocky, catshark with large and small black spots and sometimes white spots covering dorsal surface, saddle markings obsolete, small anterior nasal flaps that do not reach the mouth, no nasoral grooves, labial furrows on lower jaw only, second dorsal fin much smaller than first (Ref. 244)

A common inshore and offshore shark found on the continental shelf over rough, even rocky or coralline ground, and algal-covered bottoms. Found at depths of 1 or 2 m to at least 125 m. Feed on bottom-living invertebrates such as mollusks and crustaceans and on demersal fishes (e.g. sharks, S. canicula). Oviparous (Ref. 50449). Utilized fresh and dried salted for human consumption, and processed into fishmeal. May attain 170 cm (Ref. 27000).

Life cycle and mating behavior Maturities | Fortpflanzung | Spawnings | Egg(s) | Fecundities | Larven

Oviparous, with a single egg per oviduct (Ref. 244). Embryos feed solely on yolk (Ref. 50449). Size at hatching about 16 cm (Ref. 244).

Estimates based on models

Preferred temperature (Ref. 115969): 7.8 - 19.5, mean 10.9 (based on 836 cells).

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

Bayesian length-weight: a=0.00178 (0.00138 - 0.00230), b=3.19 (3.11 - 3.27), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.3 se; based on diet studies.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).

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

Climate Vulnerability (Ref. 125649): Moderate vulnerability (38 of 100).

Preiskategorie (Ref. 80766): Medium.
