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); sibogae: Of the ship Siboga and Indonesian expedition (1898-1899) of the same name, during which holotype was collected (See ETYFish).
Eponymy: These species are named after the ship ‘Siboga’; some after the Indonesian expedition (1898– 1899) of the same name, during which the holotypes were collected. [...] (Ref. 128868), visit book page.

50 = 0.5000 [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): 3.6 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).
Fishing Vulnerability (Ref.
