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).

生态学
海洋 深海底的; 深度上下限 600 - 1380 m (Ref. 44037). 深水域; 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.
西大西洋: 佛羅里達外的墨西哥灣東北部，坎佩切灣，巴拿馬，哥倫比亞與外海的法屬圭亞那。 已經本來被稱 Springer(1966) 的 Apristurus indicus 但是顯然地不與印度洋種同種。

Second dorsal fin distinctly larger than the first (Ref. 13608).
第二背鳍鳍明显大于第一个.(参考文献 13608)
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.
栖息于大陆斜坡了。 卵生的, 显然每个输卵管一次放置一个卵。 在墨西哥湾最普遍的 Apristurus 种, 以及 A. laurussonii 。
