The video shows a group of hippos in a river. The hippos are mostly submerged in the water, with only their heads and backs visible above the surface. The water appears to be murky and brown in color. The hippos are mostly stationary, with only slight movements of their heads and bodies. The video includes text overlays that describe the hippos' behavior, such as "Membrane covers and protects the eyes" and "Nostrils close to keep water out." The video provides a close-up view of the hippos, allowing for a detailed observation of their features, such as their large eyes and ears.
