The increase in jellyfish at Florida beaches, especially moon jellyfish (Aurelia aurita), has raised concerns among swimmers.
According to the University of Florida’s Institute of Food and Agricultural Sciences, purple flags have been raised in places like Panama City Beach to warn about marine hazards. While the proliferation of jellyfish—and their stings—are not dangerous, they can cause discomfort and temporary rashes.
Proliferation and Season
Moon jellyfish tend to proliferate in the warmer months, particularly in September and October, when conditions are ideal for their increase. Jim Masterson, a marine ecology professor, explains that their presence decreases with the arrival of cold weather.
Impact on Marine Life
These jellyfish are an important food source for turtles, birds, and fish. However, due to their limited ability to swim against currents, they are considered plankton.
Precautions for Swimmers
While moon jellyfish do not pose a major risk, swimmers are advised to wear protective suits to minimize contact. Florida is also home to more dangerous species, such as the upside-down jellyfish and the Portuguese man o’ war, whose stings can be very painful and, in extreme cases, potentially fatal.
Treating Stings
If stung, it is recommended to rinse with saltwater and apply vinegar. Freshwater should be avoided, as it can worsen the situation. Symptoms include burning, welts, and in severe cases, nausea and breathing difficulties, which require immediate medical attention.
Fun Facts
In a 1991 experiment, moon jellyfish polyps were transported to space, where they multiplied significantly. Despite their appearance, these jellyfish are considered plankton due to their inability to swim actively against currents.
With these recommendations and greater awareness about jellyfish, swimmers can enjoy Florida’s beaches more safely.
