Floating Leaves is a term used to describe the pads of aquatic plants that are able to float on the surface of the water. These pads are usually composed of thin, flat leaves that are buoyant and can remain afloat for long periods of time. The pads provide a habitat for many aquatic organisms, such as fish, amphibians, and invertebrates. They also help to keep the water clean by trapping sediment and pollutants.
