Our planet is called the blue planet because of the significant amount of water covering it (around 71%). Water supports a variety of plants and animals. Aquatic animals, also called water animals, are those that live in water. They are found in oceans, seas, rivers, lakes, ponds, and other water bodies on Earth. This article provides an overview of the names of water animals and their descriptions in detail.

How do water animals breathe?

Some small and big animals that live in wet places can breathe through their skin. This is called skin breathing, where gases pass through the skin. Animals in water often have gills, which help them take oxygen from the water as it flows over them. Gills are thin and allow gas exchange to happen.

What do water animals eat?

Water animals eat many types of food. Tiny animals like coral, sponges, and whales eat plankton, which are small water creatures. Ocean fish have different eating habits. Many eat shrimp, crabs, krill, algae, plankton, and small plants. They also eat other fish, sea urchins, and water animals like squid and octopus. Some fish eat dead animals found in the water.
