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).

Short description Chiavi di identificazione | Morfologia | Morfometria

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

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

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

Resilienza (Ref. 120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Fec assumed to be <10).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).

Price category (Ref. 80766): Low.
