Etymology: Apristurus: a-, Latin privative, i.e., without; pristis, from pristes (Gr.), sawyer (but here meaning saw); oura (Gr.), tail, referring to absence of saw-toothed crest of enlarged dermal denticles along upper edge of caudal fin as found in the closely related Pristiurus (=Galeus). (See ETYFish); sinensis: -ensis, suffix denoting place: Sinica (China), referring to its distribution in the South China Sea. (See ETYFish).

50 = 0.5000 [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).
Niveau trophique (Ref.
69278): 3.8 ±0.4 se; based on size and trophs of closest relatives
Résilience (Ref.
120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (Fec assumed to be <10).
Fishing Vulnerability (Ref.
