Teleostei (teleosts) > Gymnotiformes (Knifefishes) > Apteronotidae (Ghost knifefishes) > Apteronotinae
Etymology: Sternarchorhynchus: Greek, sternon = sternon, + Greek, archos = anus + Greek, rhyngchos = snout (Ref. 45335); inpai: Named for the Instituto Nacional de Pesquisas da Amazônia (INPA), in Manaus, Brazil.
Eponymy: INPA is the acronym for Instituto Nacional de Pesquisas da Amazônia, which helped fund the authors’ field work (Aguarunichthys inpai) and whose staff supplied Ploeg with ‘enormous amounts of material’ which served partially as the basis for his [...] (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=0.00355 (0.00145 - 0.00867), b=3.06 (2.85 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).
