Short description
Chiavi di identificazione | Morfologia | Morfometria
Diagnosed from its congeners in Europe by the possession of the following characters: origin of anal fin below or behind base of last dorsal ray; in adults, anal fin length about equal to caudal peduncle length; anal fin margin straight to convex; distance between tip of first and last branched anal rays 1.1-1.8 times depth of caudal peduncle (with fin stretched out); dorsal head profile almost horizontal above eye, then abruptly descending towards tip of snout; patches of breast scales separated by unscaled area or connected anteriorly by 1-2 rows of scales; lateral line usually reaching almost to end of caudal peduncle; in preserved individuals, flank with a midlateral row of vertically elongated blotches whose depth is about 1/3-1/2 of body depth at same position; caudal peduncle depth 2.3-3.1 times in its length; interorbital width 33-43% HL; marked hump at nape in largest individuals (Ref. 59043).
Found in clear water with moderate current, about 50 cm depth (Ref. 75055). Inhabits streams and creeks in foothills with clear and cold water, and gravel to stone bottom. Occurs in groups. Feeds predominantly on aquatic invertebrates (Ref. 59043).
