Elasmobranchii (sharks and rays) > Carcharhiniformes (Ground sharks) > Scyliorhinidae (Cat sharks) > Scyliorhininae
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): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00263 (0.00138 - 0.00502), b=3.21 (3.04 - 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): Moderate vulnerability (42 of 100).
