Description: Honeycomb Worm It was exciting to hear that the rather unusual marine worm Sabellaria alveolata had colonised the shore at Llanddulas point. Apparently it has not been recorded in North Wales for sixty years. It is a colonial creature that constructs a protective burrow by glueing sand grains together, protruding its head and tentacles when immersed. The flat, cobbled surface of the wide inter-tidal zone of this fairly exposed beach suits it admirably. Good water movement and sand at the low-tide mark enable it to build up substantial reefs near the low-tide mark.
