If you're planning a trip to the beach soon you should know scientists are recommending to be on the lookout for jellyfish. Allen Collins, a research zoologist with the National Marine Fisheries Service, says there has been an uptick in blooms of jellyfish in different parts of the world, but scientists are unsure if it's a worldwide event. More than 1,000 people were stung on a Florida beach last week, and it's possible the incidents may increase. Collins says, "When conditions are right for them to make jellies, they produce the jellyfish in vast quantities." He adds that jellyfish blooms are known to occur every 20 years, but that warmer oceans, agriculture runoff, commercial fishing and the creation of artificial reefs may have an impact on increased numbers of the animals in recent years. If you happen to get stung the experts say the first thing you should do is immediately get out of the water and use vinegar to neutralize the tentacles before trying to remove them. Also, there's no evidence that urine helps alleviate the pain from a jellyfish sting.
