Etymology: Rheocles: Greek, rheos = stream + Greek, kles, kleis = straits.
Eponymy: Franz Sikora (1863–1902) was an Austrian explorer and collector who was based in Réunion and collected in Madagascar for seven years (1890s). He discovered fossil remains of giant lemurs and early human settlers at Andrahomana Cave, Madagascar (1899). (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.3 se; based on size and trophs of closest relatives

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