Thanks for that (the first sentence especially). My references were unclear. I have seen wild comb jellies, but at Cape Cod, not in the city. I wish I understood deuterostomes and other -stomes better, and where cnidarians fit in all that; but my job is to bridge the gap between scientists and laypeople, and most laypeople don't want to know about jellyfish anuses. But that doesn't mean I shouldn't understand them.
