The Marine Monitoring Team at the Countryside Council for Wales (CCW) use video to record samples of biogenic horse mussel reef off the North Llŷn Coast. Due to the depth of the site (approx. 35m) divers have limited time and therefore quadrats are recorded on video and analysed later. This footage shows a biogenic reef teeming with life including horse mussels Modiolus modiolus, brittlestars, soft coral Alcyonium digitatum and a curled octopus Eledone cirrhosa. A rare species of sea slug, the yellow skirt slug Okenia elegans was also captured on film. This is only the second recorded sighting in waters around North Wales.
