Chondrostoma Toros
''Chondrostoma'' (from the Ancient Greek roots (''khondros'') 'lump' + (''stoma'') 'mouth' = 'lump-mouth') is a genus of Actinopterygii, ray-finned fish in the family Cyprinidae. They are commonly known as nases, although this term is also used locally to denote particular species, most frequently the common nase (''C. nasus''). The common name refers to the protruding upper jaw of these fishes; it is derived from the German (language), German term ''Nase'' 'nose'. Several species have a very restricted range. Some of these endemism, endemics are very rare nowadays, and at least one species is globally extinct. Systematics In 2007 it was determined that the presumed monophyletic group consisted of six at least partly independent lineages of Leuciscinae, meaning that the rasping feeding apparatus convergent evolution, evolved more than once. It was proposed to split the genus in six in consequence: ''Achondrostoma'', ''Chondrostoma'', ''Iberochondrostoma'', ''Pseudochondrosto ...

Common Nase
The common nase (''Chondrostoma nasus'') is a European potamodromous Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousan ... cyprinid fish. It is often simply called the nase, but that can refer to any species of its genus ''Chondrostoma''. Another name is sneep. Distribution The nase is found naturally in drainages of the Black Sea (Danube, Dniestr, Southern Bug, Dniepr), the southern Baltic Sea (Nieman, Odra (Poland), Odra, Vistula) and the southern North Sea (to Meuse in the west). Moreover, it has been introduced to the Rhône, Loire, Hérault, and Soca River, Soca/Isonzo (Italy, Slovenia) drainages. It is a migratory fish. Appearance The nase has a spindle (textiles), spindle shaped physique, with a blue-grey metallic-coloured scales and orange tail. It has relatively sharp lowe ...
