The video shows a group of capybaras, which are large rodents, swimming in a body of water. The capybaras are mostly submerged, with only their heads and backs visible above the water's surface. They are moving slowly and calmly through the water. The background consists of lush green foliage, indicating that the setting is likely a natural habitat or a wildlife reserve. The water appears to be murky, with a brownish color, possibly due to the muddy bottom or the reflection of the surrounding vegetation. The capybaras have dark brown fur, and their eyes and noses are clearly visible above the water. There is no visible title, subtitle, or informative text in the video.
