Most sea stars have spiny skin and five arms. But, surprisingly, they can grow up to 50 arms! Also, their arms are covered with pincer-like organs and suckers. These parts can allow them to creep along the ocean floor.Can they see ahead? It is a bit hard to find with a naked eye, but they have red eyes at the end of each arm!Amazingly, sea stars can grow a new arm if they lose one! This is useful if they are threatened by a predator. They can drop an arm to get away from their enemy. And then they grow a new arm. What happens to the dropped arm? It can grow an entirely new sea star! So two starfish can come from one! Isn’t it cool?These days, many people think sea stars are harmful to the marine ecosystem. 답변자 ts0068 답변일 2015-01-19 답변내용 If you look closely at a starfish, you will know that it has a unique appearance! *CORRECT!
