There were 1000s of these washed up on the beach today!

You used to be able to get a list directly from NBN but now must go to https://data.nbn.org.uk/Taxa ,click on the groups box & scroll down to Comb jelly (ctenophora).You then get 15 entries, but only 3 are UK species (P p, Beroe cucumis & Bolinopsis infundibulum).For some reason there's a 4th with "zero records",Mnemiopsis leidyi which isn't found in the UK.These are all significantly different from the sea gooseberry. See http://www.ispotnature.org/species-dictionaries/uksi/Pleurobrachia%20pileus & Beroe cucumis http://eol.org/pages/509855/overview & Bolinopsis infundibulum http://eol.org/pages/393326/media
There's 2 equally obvious Sea gooseberries similarly mis-ID'd at http://www.ispotnature.org/node/172444 & http://www.ispotnature.org/node/137091
