Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. A catshark with a prominent upturned knob on the snout, a broad head, and with no spots on the body (Ref. 5578). Yellow-brown in color, with pairs of broad, vertical, dark brown stripes outlining dusky saddles (Ref. 5578), cream ventrally (Ref. 5510).

Biology     Glossary (e.g. epibenthic)

Found on the continental shelf, from close inshore to deeper water (Ref. 244). Feeds mainly on small bony fishes and crustaceans, also cephalopods and small elasmobranchs (Ref. 244).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, with 6 to 11 egg-cases per oviduct (commonly 6 to 9) at a time (Ref. 244). Egg cases retained until embryos are well-advanced (Ref. 5578).

Estimates based on models

Preferred temperature (Ref. 123201): 15.7 - 21.9, mean 18 °C (based on 30 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.4 se; based on diet studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100).
Price category (Ref. 80766):   Low.
