Teleostei (teleosts) > Cyprinodontiformes (Rivulines, killifishes and live bearers) > Poeciliidae (Poeciliids) > Poeciliinae
Etymology: Xiphophorus: Greek, xiphos = sword + Greek, pherein = to carry (Ref. 45335).
Eponymy: Montezuma II (1480–1520), also known as Moctezuma, was Emperor of the Aztecs at the time of the Spanish conquest of Mexico. He also has two birds, an amphibian and a reptile named after him. (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=0.00851 (0.00374 - 0.01935), b=3.14 (2.95 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

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): Unknown.
