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 ) ;   exsanguis: ex (L.), out of; sanguis (L.), blood, i.e., bloodless or lifeless, referring to its characteristic pale coloration and flaccid body. ( See ETYFish ) .

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; bathydemersal; depth range 560 - 1200 m (Ref. 40896 ). Deep-water

Estimates based on models

Preferred temperature (Ref. 123201 ): 4.9 - 8.1, mean 7 °C (based on 26 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 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 ). Trophic level (Ref. 69278 ):  4.0   ±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. 59153 ):  High vulnerability (56 of 100).
