What are the adaptations of fan worms?

Fan worms, belonging to the class Polychaeta, have several adaptations that enhance their survival. Their most notable feature is the crown of feathery tentacles, or radioles, which are used for filter feeding by capturing plankton from the water. Additionally, their segmented bodies allow for flexibility and mobility, while their burrowing behavior helps to protect them from predators and environmental fluctuations. Some species also possess a hard tube made of mucus or sand, providing further shelter and stability.
