Ikan bertulang rawan (sharks and rays) > Carcharhiniformes (Ground sharks) > Pentanchidae (Deepwater catsharks)
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); canescens: Latin for hoary gray, referring to its “uniform greyish” coloration (presumably in spirits since this shark is brown in life) (See ETYFish).

Estimates based on models

Preferred temperature (Acuan 123201): 5.8 - 9.5, mean 6.3 °C (based on 13 cells).

Phylogenetic diversity index (Acuan 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).

Trophic level (Acuan 69278): 4.5 ±0.4 se; based on diet studies.

Daya lenting (Acuan 120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100). 🛈

Climate Vulnerability (Ref. 125649): Low to moderate vulnerability (34 of 100). 🛈
