Nutria

Mustelido semiacuático de cuerpo esbelto que habita a lo largo de ríos limpios, arroyos y costas de Europa y Asia. La nutria europea (Lutra lutra) puede alcanzar 1,3 metros de longitud y es una cazadora de peces altamente habilidosa, utilizando bigotes sensibles para detectar los movimientos de sus presas. Al requerir aguas no contaminadas con abundancia de peces, es una especie indicadora de la salud de los ecosistemas de agua dulce. Casi extinta en Europa Occidental por la caza y la contaminación, las poblaciones se han recuperado significativamente tras las mejoras en la calidad del agua.
