According to the National Ocean Service, the man o' war is a "species of siphonophore, a group of animals that are closely related to jellyfish."
"While the man o' war's sting is rarely deadly to people, it packs a painful punch and causes welts on exposed skin," the agency says on its website.
They also warn that the man o' war can still sting you "even weeks after having washed ashore."
