Etymology: Bythaelurus: bythos (Gr.), depths of the sea, referring to its deepwater habitat; ailouros (Gr.), cat, probably an allusion to the vernacular “catshark,” so named for its cat-like eyes (See ETYFish); naylori: In honor of Gavin Naylor, College of Charleston (Charleston, South Carolina, USA), for contributions and innovative molecular research into the higher classification of chondrichthyans and for his support of the junior author’s work in the Southwest Indian Ridge of the southwestern Indian Ocean (See ETYFish).
Eponymy: Dr Gavin Naylor is Program Director of the Florida Program for Shark Research at the Florida Museum of Natural History, where he is also Curator and Professor. [...] (Ref. 128868), visit book page.

Descrição breve Chaves de identificação | Morfologia | Morfometria
Vértebras: 114 - 128. This moderately-sized species is distinguished by the following set of characters: short snout
and bluntly rounded; preoral length 4.2-5.5% TL; oral cavity without papillae on the roof of the mouth and tongue; anal-fin base length is equal to or less than 1.5 times second dorsal-fin base length; upper caudal-fin margin with distinct enlarged dermal denticles; body colouration uniformly plain medium to dark brown, with light fin edges and a distinct dark dusky-colored snout (Ref. 102637)..
Collected by bottom trawls and midwater trawls. Maturity size for females at 48.1 cm TL and are immature at 43.0 cm TL, males at 45.2 cm and immature at 38.0 cm TL (Ref. 102637).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5001 [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).
Nível Trófico (Ref. 69278): 4.4 ±0.5 se; based on size and trophs of closest relatives
Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Preliminary low fecundity).
Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).
