Short description Chiavi di identificazione | Morfologia | Morfometria

Differs from A. grandoculis and A. microlepis for lack of a small, dark spot behind the opercle. Scales on lateral line 74-85; scale rows between the lateral line and the dorsal fin 12-14. Distinguishable from the remaining Venezuelan congeners, except A. nasutus, by its small size up to 9.15 cm SL and by the presence of a narrow, dark line that extends from behind the opercle to about two thirds of the body length (Ref. 52916).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00631 (0.00289 - 0.01377), b=3.11 (2.93 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.6 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
