Eurasian Otterユーラシアカワウソ
Lutra lutraNT— Near Threatened
The Eurasian otter is the most widely distributed otter species in the world, found across Europe, North Africa, and much of Asia in freshwater rivers, lakes, and coastal habitats. A skilled, mostly nocturnal hunter, it feeds primarily on fish, supplemented by amphibians, crustaceans, and small mammals. Once devastated by pollution and habitat loss across much of its European range, the species has rebounded strongly in places like the United Kingdom thanks to conservation efforts, and the IUCN classifies it as Near Threatened.
