What is a sea fan?
Quick Answer
A sea fan is a type of soft coral or gorgonian that grows in branching, fan-shaped colonies in marine waters.
The Full Story
Sea fans are colonial organisms made up of many tiny polyps connected by a flexible skeleton, often composed of gorgonin and sometimes calcite. Their fan-like shape helps them capture plankton and suspended particles from passing currents. They are especially common on reefs, slopes, and deeper clear waters where water movement brings food. Sea fans can be colorful and are important habitat structures for small fish, crustaceans, and other reef life.
