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); investigatoris: -is, Latin genitive singular of: HMS Investigator station in Andaman Sea, where holotype was collected. (See ETYFish).

Estimates based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00168 - 0.00717), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this Subfamily-BS (Ref.
93245).
Trophic level (Ref.
69278): 3.7 ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Fec assumed to be <10).
Fishing Vulnerability (Ref.
59153): Low vulnerability (16 of 100) .
Climate Vulnerability (Ref.
