The bristles are used to loosen and turn over the sand, and the tentacles collect particles for food and for tube building. Image: James Turner, Amgueddfa Cymru  Discover more of these remarkable images on the Up Close With Nature online gallery on 'Rhagor', the collections based website from Amgueddfa Cymru - National Museum Wales.   View On Black
