Keel worms

The keel worm is the most common and striking of the tube worms. It attaches itself to stones and other hard objects (buoys, fish crates). The Spirorbis spirorbis is often found on large brown seaweed sorts such as bladder wrack. They eat plankton, which they filter through a crown of feathery tentacles.
