الأشعة الظهرية الناعمة (المجموع): 8. Diagnosed from its congeners in Apennine Peninsula and Adriatic Sea basin by the following characters: lateral line with 58-77 + 3-4 scales; back plain and sides finely dotted in individuals larger than 15 cm SL: paired fins tinged with grey but without conspicuous spots; peritoneum white; last simple dorsal ray feebly spinous, flexible, finely serrated posteriorly; and lower lip with a median lobe (Ref. 59043).
A long-lived species which inhabits running waters of the hill and lowland zones of rivers (Ref. 26100). Also occurs in lakes. Feeds on benthic invertebrates, small fish and algae (Ref. 59043). Threatened by overfishing (Ref. 26100).
"Males assemble at spawning grounds and follow ripe females, often with much splashing, to shallow rifles. Females deposit non-sticky eggs into excavations made in gravel" (Ref. 59043).
