Growing up on Long Island Sound I saw a lot of jellyfish, usually in that shock of recognition that something NOT GOOD is coming near you in the water. There was a big Man-'O-War scare at the beach we went to when I was young, they closed down the beaches for awhile and it was the scariest thing, the alienness of them...so of course, I remain fascinated and my interest is, interestingly enough, matched by my husband (it's those similar quirks that have given this marriage wheels).
Don't want to swim with these guys but oh, how beautiful they are.
Joke: What do whales eat for lunch?
