Its reproductive strategies differ from many spring-dwelling pupfishes. Cyprinodon n. amargosae is a group spawner. Males do not establish and defend territories as do males of spring-dwelling subspecies. Instead, a reproductive male usually directs a receptive female to the periphery of the group where spawning occurs, although spawning may even take place in the center of the group (www.death-valley.us).

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=0.01349 (0.00591 - 0.03081), 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): 2.1 ±0.0 se; based on diet studies.

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