In the video, an otter is seen lying on its back on a green mat, holding a green brush in its paws and brushing its fur. The otter seems to be enjoying the brushing, as it continues to hold the brush and move it along its body. The otter's fur is a mix of brown and white, and it has a playful and curious expression on its face. The green brush has a handle and bristles, and the otter uses it to groom itself. The background is a simple wire enclosure, suggesting that the otter is in a controlled environment, such as a zoo or aquarium.
