Sea Stars
Sea stars, also called starfish, are small animals that live in the ocean. Scientists call them echinoderms. They usually have five arms, but some have more. People who study see stars have found them 20,000 feet below the ocean surface. Sometimes, you can find the sea star on the beach. Sea stars can grow a new arm when one becomes damaged or is lost; this is called regeneration. There are lots of different kinds of sea stars and depending on the type they will normally live anywhere from 10 to over 30 years.
