These two adult Aeolidia papillosa nudibranchs were on the upper shore in a shallow pool near the Guernsey origin of the Lihou Island causeway on the afternoon of 9 May 2009.  Near-by were two deposits of spawn.  The spawn is photographed in the adjacent images.  These nudibranchs feed on sea anemones - particularly beadlet and snakelocks anemones.
