Small but Innumerable, Jellyfish Storm a Beach
By LIZETTE ALVAREZ
COCOA BEACH, Fla. — They swarmed the beach, taking control of prime holiday sand and surf like a group of marauding spring breakers. Then, just like that, they vanished, leaving behind the damage: spoiled vacations, red welts, heaps of annoyance, discarded containers of vinegar and Benadryl and a crew of exhausted lifeguards.
A flotilla of mauve stingers, a kind of jellyfish that summers mostly in the Mediterranean, staked a claim on 10 miles of beach here and stayed through Memorial Day weekend, finally pulling out of town on Wednesday. The stingers — reddish and small, some no bigger than a golf ball — coated just about every inch of these beaches, sending a steady stream of screeching beachgoers to the lifeguard stations, despite warnings to steer clear.

Suddenly, surfers were donning full wetsuits in 79 degree surf. Tourists struggled to build sand castles with dry sand because the jellyfish had taken control of the wet sand. Convenience stories and pharmacies ran full out of Benadryl cream, which is used to neutralize the sting, along with vinegar.

But, with the sweltering weather and the cool surf beckoning only steps away, a few vacationers were intent on getting their money’s worth.
“We can’t tell people not to go in the water,” Mr. Scabarozi said regretfully. “So
