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).

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

Marine; bathydemersal; depth range 600 - 1380 m (Ref. 44037). Deep-water; 30°N - 6°N

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

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.

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 48.0 cm TL male/unsexed; (Ref. 244); 52.0 cm TL (female)

Short description Morphology | Morphometrics

Second dorsal fin distinctly larger than the first (Ref. 13608).

Biology     Glossary (e.g. epibenthic)

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.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 123201): 5.2 - 10.4, mean 6.4 °C (based on 83 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 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):  3.9   ±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):  Moderate vulnerability (41 of 100).
Price category (Ref. 80766):   Low.
