What Is Duckweed?

Duckweed is a type of aquatic plant that is small and grows in surface of fresh water. It is also known as water lens, bayroot, or watermeal. The plant has a yellowish-green color and its leaves are so small that they often resemble little dots. Duckweed grows in dense colonies on the water surface and can cover the entire surface of a pond if the environment is right. It is a nutritious plant that is high in protein, carbohydrates, and minerals. It also contains vitamins A, B complex, and C.

What Do Whales Eat?

Whales are some of the largest mammals on earth and have a diet to match their size. Most whales feed on krill, plankton, squid, and fish. Baleen whales, such as the humpback and blue whales, feed on tiny animals in the ocean such as krill and plankton. Toothed whales, such as the sperm whale and killer whale, feed on fish, squid, and other sea creatures. Some species of whales have been known to eat seabirds and even small sharks.

Would Whales Eat Duckweed?

The short answer is no, whales probably would not eat duckweed. Unlike krill, plankton, and other small animals, duckweed is a plant and not a source of animal protein. Additionally, the size of duckweed is too small for whales to consume. The leaves of duckweed are only 1-2 mm in size, so it would be difficult for whales to eat. Finally, duckweed is typically found in shallow, fresh water, while whales live in the deep ocean.

Why Is Duckweed Important?

While whales may not eat duckweed, the plant is still important for aquatic ecosystems. Duckweed is a source of food for many animals such as fish, ducks, and turtles. The plant also helps to keep water clean by absorbing excess nutrients and pollutants, which can prevent algal blooms. Duckweed can provide habitat for fish and other aquatic animals, and its roots help to reduce erosion in rivers and streams. Finally, duckweed can be a valuable source of food and fodder for humans and animals alike.


In conclusion, whales would not eat duckweed due to its small size and lack of animal protein. However, duckweed still plays an important role in aquatic ecosystems and can be a valuable source of food for humans and animals. As the world continues to face environmental challenges, it is important to recognize the importance of plants like duckweed in sustaining life on earth.
