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); parvipinnis: parvus (L.), small; pinnis (L.), fin, referring to first dorsal fin 2-4 times smaller than second dorsal fin (See ETYFish).

Οικολογία
Θαλασσινό(ά) βαθύβιο(ς); εύρος βάθους 600 - 1380 m (Ref. 44037). Deep-water; 30°N - 6°N
Western Atlantic: northeastern Gulf of Mexico off Florida, Gulf of Campeche, Panama, Colombia, and off French Guiana. Had been originally termed Apristurus indicus by Springer (1966) but apparently not conspecific with the Indian Ocean species.

Γεννητική Ωρίμανση: Lm ? range ? - ? cm
Max length : 48.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 244); 52.0 cm TL (female)
Second dorsal fin distinctly larger than the first (Ref. 13608).
Body shape (shape guide): elongated.
Found on the continental slope. Oviparous, apparently laying one egg per oviduct at a time. The most common Apristurus species in the Gulf of Mexico, along with A. laurussonii.
