A jellyfish-like marine cnidarian of the family Physaliidae. Its venomous tentacles can deliver a powerful sting.



The Portuguese man o’ war (Physalia physalis), also known as the Portuguese man-of-war, Man-Of-War, or bluebottle, though often mistaken as a jellyfish, is a marine cnidarian of the family Physaliidae. Its venomous tentacles can deliver a painful sting.

Despite its outward appearance, the Portuguese man o’ war is not a jellyfish but a siphonophore, which differs from jellyfish in that it is not actually a single multicellular organism but a colonial organism made up of many highly specialized minute individuals called zooids. These zooids are attached to one another and physiologically integrated to the extent that they are incapable of independent survival.
