I cracked up when I saw this sign b/c it reminds be of guys, j/k. Seriously though, this is an interesting fact of the day. For some reason, I thought animals needed brains, if not also hearts. I didn't see any jelly fish in the Wizard of Oz. Hmm...

PS. I must give credit to marquema. That's where I first saw a cool picture of jelly fish, which inspired me to imitate the same pic. Not only is it amazing to capture, but also identify, something beautiful and/or interesting.
