NEWSPHOTOS: 7 'Jellyfish' that can be found at the beach in Northwest FloridaComb jellyfish What are they: Little translucent jellies, you've probably seen them on both the Bay and Gulf side of St. Andrews State Park if you look closely. Do they sting: No, they don't have tentacles and instead have sticky cells to hunt their prey.Northwest Florida Daily NewsPink Meanies What are they: Yes, that's their name. A relatively new species of jellyfish, discovered in 2011 in the Gulf of Mexico, these guys are known for feeding on other jellyfish, and even other Pink Meanies! Do they sting: Yup. Their tentacles can grow up to 80 ft. long and they will give you a sting worthy of the name "meanie."Northwest Florida Daily NewsMoon jellyfish What are they: Rather serene looking, these moon jellies are another frequent visitor to the kiddie pool at St. Andrews State Park, where kids (and adults) have fun poking their tops Do they sting: Not usually. Their stinging cells are not usually enough to harm humans, but they may cause some irritationNorthwest Florida Daily NewsBlue Button What are they: Not technically a jellyfish, this little guy is also a colony of organisms. It's official name is also Porpita Porpita, which is frankly adorableNorthwest Florida Daily NewsMan o' War What are they: Another cluster of organisms and not a true jellyfish, the Man o' War is actually a group of orgaisms acting as one to survive. They're so named because the top "sail" sits on top of the water and resembles a warship at full sail. Do they sting: YES. Man o' War have incredibly long tentacles (up to 100ft!) and they pack a wallop that may send someone to the ER if they have a reaction. STAY AWAYNorthwest Florida Daily NewsSea Nettle What are they: A jellyfish with a range from the Chesapeake Bay all the way to tropical waters, this carnivorous jellyfish can, at certain stages, reproduce all on its own. It has the look of a typical jellyfish and can be a variety of different colors depending on where it's found. Do they sting: Yes. The tentacles will produce a moderate sting that is not deadly but is certainly uncomfortable. They sting using a different mechanism than other organisms like the Man o' War and as such, vineagar may be an effective treatment to disable the stringing cells. Heat is also recommended to break down the toxin.Northwest Florida Daily NewsDo they sting: Not humans. The Cannonball Jellyfish uses a weak toxin to hunt fish, but that toxin does not usually sting humans. However, the toxin can cause irregular heart rhythms in those with cardiac problems, so steer clear if you can. Some cultures even eat Cannonball Jellyfish!Northwest Florida Daily NewsCannonball Jellyfish What are they: Also known as Cabbagehead Jellyfish, these big guys are proper jellyfish with heads that can be up to 10 inches in diameter and a small cluster of arms underneath.
