Etymology: Halaelurus: halos (Gr.), sea; ailouros (Gr.), cat, probably an allusion to the vernacular “catshark,” so named for its cat-like eyes (See ETYFish); natalensis: -ensis, Latin suffix denoting place: the coast of Natal, South Africa, type locality (See ETYFish).

Estimates based on models
Preferred temperature (Ref. 123201): 15.7 - 21.9, mean 18 °C (based on 30 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5078 [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).
营养阶层 (Ref. 69278): 4.2 ±0.4 se; based on diet studies.
回复力 (Ref. 120179): 低的, 最小族群倍增时间4.5 - 14 年 (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153): Moderate vulnerability (37 of 100).
