Over one thousand swimmers stung by jellyfish in Florida

You can call it the attack of the jellyfish as it is something out of a horror show.  Uncountable numbers of purple jellyfish are attacking swimmers and over 1,600 people have already been stung.
These could be alien jellyfish, at least alien to North America. Monty Graham of Alabama's Dauphin Island Sea Lab said "They're much more common in the Mediterranean.  Probably what we're seeing is a large population bloom in the Gulf of Mexico transported by the Gulf Stream wrapping around the coast of Florida."
Beaches between Cape Canaveral and Cocoa Beach have been flagged showing a hazard and warning against "dangerous marine life."
These jellyfish are quite different as they also have potent stinging cells on the top of their body, where most jellyfish do not have them.
Vinegar is used to treat the stings.  Lifeguards on one beach used twenty five gallons of vinegar in helping those who were stung.
