brown beaver near green grasses

On my recent canoe trip in a german area called "Spreewald", my friends and me spotted this little animal here next to us in the grass. We all thought it was a beaver and we were so hyped about it. He was so calm and let us came pretty close to him. At the end of the day I found out that it isn't a beaver - It is a nutria (also called coypu)! Typical for these animals are the large, bright orange-yellow teeth (incisors).
