The Portuguese Man O’ War
Jellyfish have an extremely powerful and painful sting, and the Portuguese man o’ war is often associated with this species because it has a similar way of attacking. But unlike most jellyfish stings, this creature’s particular jab will introduce a toxin into the body that has proven to be fatal in adults, children and animals. Ironically, the Portuguese man o’ war is actually a colony of tiny organisms and not a whole creature like other jellyfish.
