Short description Morphology | Morphometrics

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.

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

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00324 (0.00157 - 0.00666), b=3.11 (2.93 - 3.29), 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. 69278): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).

Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100) .

Price category (Ref. 80766): Low.
