Rare blue jellyfish-like creatures landed in New Jersey, confusing beach tourists.

A jellyfish-like creature, Porpita Porpita, was washed ashore. Strange bright blue creatures with feathery tentacles are being washed up on the beach in New Jersey. Surprisingly, according to news reports, people on the beach are not used to seeing blue-green spots dotted on the coast.

These jellyfish-like creatures are often called Porpita Porpita, but they are not native to Garden State. On the contrary, Hurricane Florence took tropical animals away from the Gulf Stream, a powerful ocean current in the Atlantic Ocean, and pushed them north to the east coast.

This is something I have never seen before. I have been walking on Na Pianhai Beach since 10 years old. "I'm 55 years old now," Holly Horner, a professional wildlife photographer from Egg Harbor, New Jersey, told Asbury Park Press after finding blue buttons on a beach in Brighton last week.

Although it looks like a jellyfish, the blue button is another kind of creature (or rather, a group of creatures). They belong to the scientific class of Hydra, and each member of Hydra is composed of Hydra community. Hydrozoa are small carnivores related to jellyfish. According to National Geographic, the most famous hydra is probably Portugal's Physalia physalis, which can emit a stinger, which is very powerful and can kill fish and even harm humans.

But the blue button is not as dangerous as the Portuguese war. Paul Bologna, an associate professor of biology at Monclair State University in New Jersey, told Asbury Park Press: "Because the blue button has a slight tingling sensation, it will * * * skin, but it is not so dangerous to humans. Despite this, the sting of the blue button is enough to keep the animals well nourished. " . The round yellow-brown "button" part of the blue button is usually about an inch wide and has tentacles hanging on it. According to Life Encyclopedia, this button is inflatable and can help the blue button float in the water. According to the National Park Service, these lines or watery branches can kill free-floating marine animals, called zooplankton, and the blue button will eat them at dinner.

This map shows the bays and rivers in the North Atlantic. Hurricane Florence hit Carolina last month, and the blue button in New Jersey may have been taken away from the Gulf Stream by Hurricane Florence. Bologna added that he had seen blue buttons on the Florida coast, but never in New Jersey. "Most likely, when the water temperature drops, they will all die, so they may stay for a few more weeks," Bologna told reporters in Asbury Park. Generally speaking, they are not dangerous, but like all jellyfish, they also have stinging cells, so caution is always the best choice.
