The man o' wars (men o' war?) are coming for us.
The murderous siphonophore was removed from the beach and no one was injured, but remember: Their venomous tentacles can remain dangerous for hours or even days after their deaths, so if you find one, do not put it on your baby or try to wear it as a hat!
An unrelated though still relevant fact: Blanket octopi are immune to the man o' war's sting, and tend to capitalize on this by collecting their tentacles and wielding them as weapons to fend of predators.
The ocean is a terrifying place you're probably better off avoiding. Might as well steer clear of New Jersey too.
