Upside Down Jellyfish?

[rlskill1]

We were snorkeling in the back waters at DuBois County Park at Jupiter Inlet, Florida. We came across a creature that looks like an upside down jellyfish in the water on the bottom. We tried to see it's underside, and it went back to it's original position. I found 2-3 of them as we were snorkeling. They ranged in size of 12" in diameter to the smaller one that was 2-3" in diameter. Any ideas? Do Sea Pansies get this large?

I'm on my phone so no links bu check wikipedia. They have the upside down jellies on display in Monterey aquarium here. They do exist.

You can see one at 2:55 in this video (watch in non-HD if on a slower connection!) from our trip to Roatan:

Had never seen them before, but they're pretty neat.

We saw upside down jellys in Bonaire on a kayak/snorkel trip. They fit your description.
