Kneriidae (Shellears)
Etymology: Kneria: From Kner, that studied fishes in the Imperial Museum of Vienna, with Jean Natterer (1817) (Ref. 45335); ruaha: Named for the Ruaha River drainage, Tanzania, where it occurs; noun in apposition (Ref. 26644).
Environment: milieu / climate zone / depth range / distribution range

Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.

Nível Trófico (Ref.
69278): 2.0 ±0.00 se; based on food items.
Fishing Vulnerability (Ref.
