The Sea Plate Car Sea Star, also known as the Sunflower Sea Star, is the largest known sea star in the world. In the Yellow Sea and Bohai Sea of our country, there is a type of starfish called the sea disk car. Its body is flat and shaped like a five pointed star, with a long wrist and suction cups on its legs. When this starfish moves, it is like a pole vaulter, first using suction cups to suck the ground, then supporting its body to flip and move forward one step, and then continuing to repeat this action, moving forward little by little. The diameter of the Sea Plate Car starfish is 80cm, making it the largest starfish in the world. It lives in the Pacific Ocean and has a huge stomach in the middle. Unlike other starfish, it has 24 antennae.
