Rhizostoma pulmo seen in the Marine Lake, West Kirby, Wirral, Merseyside, in the last week of October 2011. Probably washed into lake at high tide. Very beautiful, healthy and probably feeding on plankton in very shallow water at edge of lake. Caused a stir, everyone photographing it, I have never seen this species before in these waters.
