Teleostei (teleosts) > Cyprinodontiformes (Rivulines, killifishes and live bearers) > Goodeidae (Splitfins) > Goodeinae
Etymology: Allotoca: Greek, allos = other + Greek, tokos = birth (Ref. 45335). The transliterated Latin terminal part of the compound name ('tocus') was changed to 'toca', thus the genus is feminine (Ref. 35111); zacapuensis: Named for its known distribution, the basin Lagoon de Zacapu (Ref. 42981).

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; demersal; pH range: 7.0 - 7.0. Tropical; 17°C - 20°C (Ref. 42981)

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01230 (0.00475 - 0.03188), b=3.01 (2.79 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.5 ±0.1 se; based on size and trophs of closest relatives

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