Etymology: Astyanax: The name of Astyanax, Hector´s son in the Greek mythology (Ref. 45335).
Eponymy: Astyanax was the son of Hector in Greek mythology. See Homer’s Iliad for details. The reasoning for its use for a genus of characins is not explained. Dr John Francis Bransford (1846–1911) was an assistant US naval surgeon (1872–1890) on the Nicaragua and Panama Canal surveys (1872–1888). [...] (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01096 (0.00493 - 0.02437), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.8 ±0.60 se; based on food items.

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

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