Etymology: Cnesterodon: Greek, knester, -eros = scraper (Ref. 45335); pirai: The specific epithet pirai derives from the Guarani words “pirá”, meaning fish and the diminutive “í”, in allusion to the small size of the fishes belonging to the genus Cnesterodon. A noun in apposition.
Eponymy: This is not an eponym: Pirai is derived from the Guarani words that translate as ‘little fish’. (Ref. 128868), visit book page.

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00342 - 0.03356), b=3.08 (2.82 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.0 ±0.4 se; based on size and trophs of closest relatives

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