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); dawsoni: In honor of Elliot W. Dawson (b. 1930), National Museum of New Zealand (now Museum of New Zealand Te Papa Tongarewa), who brought the first specimens to Springer’s attention (See ETYFish).
Eponymy: Elliot Watson Dawson (1930-2020) was a biologist with the New Zealand Oceanographic Institute of the New Zealand Department of Scientific & Industrial Research (1955–1990), principally involved in carrying out surveys of the marine benthic fauna of [...] (Ref. 128868), visit book page.

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).

Trophic level (Ref. 69278): 3.4 ±0.53 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (35 of 100).
