Kurzbeschreibung
Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt): 0; Rückenflossenweichstrahlen (insgesamt): 0; Afterflossenstacheln 0; Afterflossenweichstrahlen: 0. Bright yellow or golden spots on a dark grey body with irregular blotches and saddles (Ref. 5578), cream below (Ref. 5510); 2nd dorsal much smaller than 1st (Ref. 5578). Small anterior nasal flaps that do not reach mouth, no nasoral grooves (Ref. 244).
A common inshore to offshore catshark. Prefers to feed on small bony fishes and crustaceans, also cephalopods (Ref. 244). Oviparous (Ref. 50449).
Oviparous, with a single egg per oviduct at a time (Ref. 244). Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Size upon hatching below 31 cm (size of young with umbilical scars) (Ref. 244).

Estimates based on models
Preferred temperature (Ref.
123201): 9.3 - 16.5, mean 12.2 °C (based on 45 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00263 (0.00139 - 0.00497), b=3.21 (3.04 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.5 se; based on diet studies.
Widerstandsfähigkeit (Ref.
120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Fec = 1).
Fishing Vulnerability (Ref.
