Aquatic Plants Classification

Free-floating plants are small plants that float on water surface, and they are mostly found in ponds and lakes where the water remains stagnant.

Duckweed, water lettuce, and water hyacinth are examples of free-floating plants.

Fish breathe through gills, while whales and dolphins breathe using their lungs and through nostrils on the top of their head, known as a blowhole.
