Marine biologist Alan Deidun shared a photo sent to him by colleague Alessio Marrone of a serpulid worm, known for their ‘feathery displays’.
The worms have a ‘crown of feeding tentacles which scoop up planktonic prey off the water column’.
They are also known for their calcium carbonate tubes, which persist long after the worm is gone.
Have you ever spotted one?
