The Bearn beaked dace (Leuciscus bearnensis) is a putative species of cyprinid fish, recorded from several localities in the Adour drainage in France.
Description
[edit]The Bearn beaked dace is distinguished from other western European members of the genus Leuciscus by having a keel which runs from its nape to the origin of the dorsal fin, a projecting snout which has a rounded tip and a projecting upper jaw, the dorsal profile of head and body shows a distinct hump; the snout is 32-35% of the length of the head; and the lateral line has around 47-52 scales.[2] It also has thick, fleshy lips and a large eye, the diameter of them being approximately a fifth to a quarter of the length of the head. It grows to 280mm in standard length.[4]
Distribution
[edit]The Bearn beaked dave occurs only in the drainage basin of the Adour in south-western France[4]
Habitat and ecology
[edit]The Bearn beaked dace is found in streams, especially in sections of the streams which have clear water and current with cool, deep pools.[1]
