Elasmobranquios (tiburones y rayas) (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); bachi: In honor of Johann Sebastian Bach (1685-1750), a “musical genius and one of the greatest composers of all time” (so named because the senior author admires Bach and not for any Bach-like feature the shark might possess, Simon Weigmann, pers. comm.) [see also B. vivaldii]. (See ETYFish).

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 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 4.3 ±0.5 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Preliminary low fecundity).

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