Do any animal or plant can float on the surface of a pond?

Yes, several animals and plants can float on the surface of a pond. For example, many species of water lilies and duckweed are aquatic plants that thrive on the water's surface, while animals such as frogs and certain insects like water striders can also be found floating or resting on the water. These organisms have adaptations that allow them to stay buoyant, such as air-filled structures or lightweight bodies.
