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).

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).

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

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Fec assumed to be <100).

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