Etymology: Bathybagrus: Greek, bathys = deep + Greek, pagros = a fish (Dentex sp.) (Ref. 45335).
Eponymy: Rudolf Grauer (1870–1927) was an Austrian explorer and zoologist who collected extensively during an expedition to the Belgian Congo (1909) and again (1910–1911) on an expedition paid for by the Austrian Imperial Museum. [...] (Ref. 128868), visit book page.

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Nivel trófico (Ref. 69278): 4.3 ±0.75 se; based on food items.
Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).
