Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 13 - 21; Anal spines: 0; Anal soft rays: 12 - 23. The filamentous last dorsal fin rays distinguish it from any other eastern Pacific genus. Separated from other eastern Pacific Opisthonema by having only 25 to 36 lower gill rakers in fishes over 14 cm standard length.

Forms schools. Apparently the least abundant of the eastern Pacific species of Opisthonema. Feeds on crustaceans and pteropods. Caught along with the other species of the genera.

Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 28.6, mean 27 °C (based on 34 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00871 (0.00415 - 0.01826), b=3.06 (2.89 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.38 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Low.
