Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0. A shyshark with dark markings with large light spots without black edges on a yellowish-brown body and on fins; body also with 7 dark brown or blackish dorsal saddles (Ref. 5578).

Biology     Glossary (e.g. epibenthic)

Inhabits the continental shelf, in inshore waters (Ref. 244). Most common in shallow sandy areas (Ref. 244). Feeds on small bottom-dwelling fish, crustaceans, and cephalopods (Ref. 27121). Oviparous (Ref. 50449). Caught by shore anglers (Ref. 5578).

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

Oviparous, with 2 egg-cases at a time, hatching at about 11 cm (Ref. 5510). Embryos feed solely on yolk (Ref. 50449).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00175 - 0.00721), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.59 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (43 of 100).
Price category (Ref. 80766):   Low.
