Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. Body with a reticular pattern of narrow dark lines (Ref. 13577). Caudal fin with its upper lobe hardly elevated above the body axis, with a strong terminal lobe and subterminal notch but no ventral lobe (Ref. 13577).

Biology     Glossary (e.g. epibenthic)

A little-known shark (Ref. 247) found on the continental shelf and offshore reefs (Ref. 6871). Probably feeds on bottom fishes and invertebrates (Ref. 13577, 43278); also known to eat nocturnal teleost fishes such as squirrelfish and soldierfish (Holocentridae) and sweepers (Pempheridae) (Ref. 43278). Ovoviviparous (Ref. 50449). Might bite in self-defense or when mistaking a human foot for its usual prey (Ref. 247). Its tough skin sometimes used for leather (Ref. 13577). The maximum length of 366 cm TL reported for this species is uncertain (Ref. 247, 90102).

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

Ovoviviparous, embryos feed solely on yolk (Ref. 50449).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 26.2 - 28.8, mean 27.8 (based on 294 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.60 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Very high vulnerability (86 of 100) .
