Biology     Glossary (e.g. epibenthic)

A common catshark found on the continental shelf, from close inshore down to at least 100 m (Ref. 244, 11230). Interest to fisheries unknown (Ref. 11146). Oviparous (Ref. 50449).

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

Oviparous, with only one egg laid per oviduct at a time (Ref. 244). Embryos feed solely on yolk (Ref. 50449). Size at hatching at least 8 cm (Ref. 244). During courtship and prior to copulation, the male bites and wraps the female's pectoral fin, body, tail, and gills (Ref. 49562, 51119). Copulation is initiated when the male inserts one of its claspers into the female's cloaca. The whole mating episode lasts from 15 seconds to 4 minutes (Ref. 49562).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00324 (0.00157 - 0.00666), b=3.11 (2.93 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.9   ±0.61 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Fec = 1).
Vulnerability (Ref. 59153):  Moderate vulnerability (38 of 100) .
