Europe: Rhône drainage, except Lake Geneva basin (France, Switzerland). Originaly widespread, but following habitat alterations, distribution is now much fragmented and restricted. Main subsisting populations in the middle Doubs (France, Switzerland) and Durance and Ardeche (southern France).
歐洲: 羅恩河流域。

簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 8 - 13; 背的軟條 (總數): 10-14; 臀棘 1-3; 臀鰭軟條: 8 - 12; 脊椎骨: 43 - 45. The presence of 57-65 + 3-6 scales along lateral line distinguishes uniquely this species from its congeners. Can be further separated from other species by the combination of the following characters: first dorsal fin with 8-9 spines; second dorsal fin with 1-2 simple and 9-12½ branched rays; scaleless cheeks (Ref. 59043). Caudal fin with 17 soft rays (Ref. 40476).
尾鰭有 17個軟鰭條。 (參考文獻 40476)

生物學特性     字彙 (例如 epibenthic)

A short-lived species reported to live in fast-flowing rivers with a gravel substrate (Ref. 30578). Occurs in main course of rivers and large streams and in riffles. Found on stone bottom (Ref. 59043). Lurks on the bottom during the day and comes out for crepuscular feeding (Ref. 11941). Feeds on aquatic invertebrates. Larvae feed on plankton under surface, then at about 2.5 cm SL, they move to benthic habitats. Attains first sexual maturity at 2-4 years of age. Spawns in deeper parts of riffles. Deposits on gravel strongly adhesive eggs, 2.2 mm in diameter, which hatch in about 14 days at 13° C (Ref. 59043). Threatened due to habitat destruction and pollution (Ref. 26100).

一種生命期短的種是發現於快速流動的河具有一個礫石底部.(參考文獻 30578) 然後變成底棲的它何時達到 2-2.5 公分的大小,最初大洋性。 產卵在三月到四月,在石頭或植物之上。 在底部上的潛伏在白天期間而且為晨昏的進食出來.(參考文獻 91141) 吃小型無脊椎動物,昆蟲幼生與小型甲殼動物。 (參考文獻 30578) 受到威脅的由於棲息地破壞與污染.(參考文獻 26100) 非常稀有的魚.(參考文獻 30578)
