Alright, another strange Jellyfish question. This occurred in Viareggio, again in Italy, durring the early summer of last year. I was swimming in the sea, in which at first I did not see a single jellyfish, when all at once I was swimming in what was something like two parts jellyfish to one part water, if you get my drift. I know that now sudden blooms of medusae in the Mediterranean have been becoming common, but here's where it gets a little weird: every last one of them were dead, and their tentacles missing. What could have caused this? At first the only explaination I could think up was that perhaps they die after breeding, and that their tentacles had been chewed off. Which, nonetheless, makes little sense to me. And seeing that a creature whose body is 97% water decays quite rapidly as it is, I wouldn't think that their tentacles just happened to rot away first. I supposed it's worth noting that, although varying in size, all of the dead jellyfish were of the same species. All other types of jellyfish I saw that day in the area were alive and intact. Any ideas?
