Краткое описание
определительные ключи | морфология | морфометрия
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).

50 = 1.0625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00417 (0.00157 - 0.01110), b=3.08 (2.85 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

устойчивость к внешним воздействиям (Ref.
