Characteristics a Otter uses to survive today and for the future. Today Otters have thick, protective fur to help them survive in the cold water. Also the Otters have short and webbed feet to help them swim. And also have a narrow body with a flattened head for good movement in the water. And a long tail to propel them through the water. Now for the future, since I think that a lot of trees will be cut down, they will have to rely on shrubs for houses. And since they have to rely on shrubs for shelter they are going to have to use a lot of it to stay warm even with their warm fur. And I think if more shrubs are next to them they will start eating plants.
