Elasmobranchii (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); alcockii: In honor of physician-naturalist Alfred William Alcock (1859-1933), who noted the distinctiveness of this species in 1896 (See ETYFish).
Eponymy: Lieutenant-Colonel Dr Alfred William Alcock (1859–1933) was a British physician, herpetologist, carcinologist and naturalist. [...] (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=0.00347 (0.00171 - 0.00701), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
4.1 ±0.4 se; based on size and trophs of closest relatives |
|
Resilience (Ref. 120179) |
Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100). |
