Otter (Lutra lutra)

This typical semi-aquatic animal is a common inhabitant of the Danube anywhere where there is an abundance of its food - fish, amphibians, and small birds. Although it is generally believed to live only in fast, clear, mountain streams, research has found that it usually goes into slow-flowing rivers like the Danube, if there is enough food and hiding places in and around the river.

Nutria (Myocastor coypus)

This South American rodent made sure not to have an ideal situation on the Danube! This non-European semi-aquatic species miraculously crept into our fauna, finding a very favorable habitat for reproduction. The main habitat in Serbia is the Danube, which allows easy living for this species – lots of food, hiding places and protection from enemies. High reproduction of this large South American rat threatens to jeopardize any aquatic ecosystem, even as strong as the Danubian.

Common Noctule (Nyctalus noctula)

Members of this species are frequently observed in riparian forests along the Danube. They stay in the hollows of old willows, poplars and other trees, and find food high above the water's surface. Although not particularly related to the water surface like some other species of bats, the valley of the Danube River is the main migration corridor of Noctules and the species stretches over a distance of more than 1,000 kilometers during the spring and autumn migrations. In those periods, especially in late afternoon and evening hours, small and big flocks of noctules can been seen and heard flying in haste to reach their summer or winter habitat.
