Etymology: Scyliorhinus: skylion, Greek for dogfish or small shark; rhinus, from rhine (Gr.), rasp, alluding to a shark’s jagged, rasp-like skin. (See ETYFish); boa: Presumably referring to its reticulated brownish markings, similar to those of a boa constrictor. (See ETYFish).

Estimates based on models
Preferred temperature (Ref. 123201
): 8.9 - 15.1, mean 11 °C (based on 20 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00275 (0.00140 - 0.00542), b=3.20 (3.02 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.5 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. 59153
