Etymology: Asymbolus: Etymology not explained, possibly a-, Latin privative, i.e., without; sym-, from syn (Gr.), together or joined; bolus (L.), lump or morsel, proposed as a subgenus of Scyliorhinus (Scyliorhinidae) distinguished in part by labial fold of upper lip not hanging over lower-jaw symphysis of A. analis and A. vincenti (See ETYFish); analis: Latin for anal, probably referring to its anal fin, which is larger than second dorsal fin (See ETYFish).

Estimates based on models
Preferred temperature (Ref.
123201): 16.4 - 20.5, mean 17.9 °C (based on 134 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [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.

Trophic level (Ref.
69278): 4.3 ±0.6 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).
Fishing Vulnerability (Ref.
