Short description
Morfología | Morfometría
Can be diagnosed from its congeners in Europe by the following combination of characters: caudal fin slightly emarginate; dorsal fin origin above or slightly in front of pelvic fin origin; caudal peduncle depth 1.1-1.6 (usually 1.3-1.4) times in its length, 1.2-1.5 times in body depth; back between nape and dorsal usually with 2-4 irregular dark blotches (Ref. 59043).
Facultative or obligate air-breathing (Ref. 126274); Inhabits streams with gravel to stone bottom (Ref. 59043).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00336 - 0.01491), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 2.8 ±0.3 se; based on size and trophs of closest relatives
Resiliencia (Ref.
