Short description Bestämningsnycklar | Morfologi | Morfometri

Dark brown dorsally, slightly paler ventrally (Ref. 391).

A little-known inshore bottom shark of the continental and insular shelves. Well adapted to lie amongst coral reefs due to its tough skin (Ref. 391); depth data not available (Ref. 43278). Breeding and feeding habits are unknown. Presumably oviparous (Ref. 50449). Survives for many hours out of water (Ref. 391).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00417 (0.00157 - 0.01105), b=3.08 (2.85 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.8 ±0.3 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).

Price category (Ref. 80766): Unknown.
