Of the hundreds of thousands of photographs that I've taken, this is definitely one of my favorites.
Not much of a story-- I used to live in South Florida for 20 years. The beaches are a major draw of course. We don't have many jelly fish, but we do get a bunch of these guys - Portugese Man-O-War... They're like Jellyfish, except instead of swimming around, they just float, and sting their prey as it swims through their tentacles.
There's the occasional swarm of baby Man-O-War, which don't float as much.... aren't as noticeable, so you just come out of the water with a bunch of stings on you..... And then there's what you see here, they wash up on the shore.
Enjoy the photo. And... If you see one of these on the beach, don't step on it!
