Coral comes in many pretty colors and shapes. Some coral is bright pink, while others are orange, yellow, or blue. The shape of coral can look like branches of a tree, a fan, or even a brain! Some coral grows flat like a table. Others look like fingers pointing up. The colors come from tiny algae living inside the coral. These algae also give coral food. The shapes help coral catch food and stay safe from waves and animals that might eat them.
