South-west European nase

Description

The South-west European nase (Parachondrostoma toxostoma) is a slender-bodied fish,with a short snout and a somewhat conical head.The arched,horseshoe-shaped mouth has a thin,horny layer on the lip and a small row of teeth,making it well adapted for scraping algae from the surface of stones.Generally olive green with silvery flanks,the South-west European nase develops a dark band along the sides during spawning.The dorsal and caudal fins are grey,while the pectoral, pelvic and anal fins are typically yellowish.
