The nase has a spindle shaped physique, with a blue-grey metallic-coloured scales and orange tail. It has relatively sharp lower lip. Generally, the fish range from 25 to 40 centimetres in length, and weigh about 1000 grams. However, specimens have been recorded up to 60 long and 3 kg in weight . The maximum recorded life span of the fish is 15 years.
This gregarious species is found in deep water with a fast current, often in the back waters of bridges or in rocky outcrops. It dwells near the bottom where it feeds on algae, aquatic plants and invertebrates. Nase fish on the whole stay in shoals.
The nase is protected by the Convention on the Conservation of European Wildlife and Natural Habitats.
