Etymology: Brachyhypopomus: Greek, brachys, eia = short + Greek, hypo = under + Greek, poma, -atos = cover (Ref. 45335); pinnicaudatus: Specific name is derived from the Latin pinna, meaning feather, and caudatus, meaning tailed, because of the distinctive compressed and "feather-like" appearance of the caudal filament of the male..

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=0.00380 (0.00145 - 0.00994), b=3.06 (2.83 - 3.29), 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

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

Price category (Ref. 80766): Unknown.
