About Feather Duster
This animal does not look much like a worm at all but looks more like a flower. It lives in a tube of mud and sand under the water that sticks up from the seabed. When it feeds, it extends delicate tentacles from the top of the tube, trapping any edible particles that drift within its reach. If the duster’s feathery tentacles are touched, or if a shadow passes over them, they will vanish into the tube.
