Sea fans are a type of soft coral found in warm, shallow waters, particularly in the Caribbean Sea and Pacific Ocean. They have a flat, fan-like shape and are made up of tiny polyps that live in colonies. These corals come in various colors, including yellow, pink, and purple, and they play a crucial role in marine ecosystems by providing habitat and shelter for small fish and other marine organisms. Unlike hard corals, sea fans do not build reefs but instead rely on water currents to bring them nutrients. They are sensitive to changes in their environment, such as water temperature and pollution, making them important indicators of ocean health. Conservation efforts are essential to protect these beautiful creatures and their habitats.
