There are two main types of coral: hard coral and soft coral. Hard coral builds a tough shell made of limestone. It grows in shapes that look like branches, fans, or round domes. Soft coral doesn't make a hard shell. It looks more like plants with bendy branches. Some soft corals wave in the water like trees in the wind. Both types of coral are home to small animals called polyps. These polyps work together to get food and stay safe.
