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); macrostomus: macro-, from makros (Gr.), long or large; stomus, from stoma (Gr.), mouth, allusion not explained, perhaps referring to its having the widest mouth among its South China Sea congeners. (See ETYFish).

Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD

Nível Trófico (Ref.
69278): 3.8 ±0.4 se; based on size and trophs of closest relatives
Resiliência (Ref.
