Jellyfish are strung out all along the water, and even up into what appears to be dry sand for the first 5 feet or so. Out in the water, YouTube had videos showing Cannonball Jellyfish (never heard of them but glad to catch the name).
The type at the end of Johnson Avenue in Cape Canaveral and I know up to Lori Wilson Park are a purple looking jellyfish, 1 to 2 1/2 inches in diameter, with purple tentacles, 8 of them according to Wiki, but it was hard to see all of them.
One of our local surfers got nailed at the end of our street. And I know of someone else that got it in back of one of the resorts south of Lori Wilson Park in Cocoa Beach.
Keep your Vinegar or Ammonia bottle sprayer handy in the car. Sudsey Ammonia with half water added did the trick for me once, but the resorts keep Vinegar in a bottle to spray you which works well also.

16streets.com had a pretty good write up on the situation with the Jellyfish and what type they are.
