Feather Duster Worms [Serpulidae]

Description

Serpulidae, also known as feather duster worms, are a family within the order Terebellida characterized by their calcareous tubes and distinctive feather-like gills. These gills serve both for respiration and feeding, capturing plankton and detritus from the water column. Serpulidae are sedentary, attaching themselves permanently to substrates, including rocks, shells, and even the hulls of ships. Their colorful gills, which retract when threatened, contribute significantly to the biodiversity and aesthetic value of coral reef ecosystems.
