As the name suggests, starfish are star-shaped animals usually found in water. But starfish are not actually fish. They do not have a backbone and belong to a class of animals called invertebrates. Over 1600 various types of starfish live in the oceans of the world. They differ in color, shape, and size.
Starfish have neither blood nor a brain. Their bodies are filled with seawater. This seawater carries out the functions of the blood in their bodies. Starfish have tough leathery skin that protects them from their surroundings. They also have multiple tiny feet at the end of their arms, which help them crawl on the ocean floor. Their eyespots are located at the end of their arms and help them identify various shades of light. These eyespots help them look for food in the ocean.
