Physalia Physalis

23, Norway. Art, my drawings and whining, things I like and occasional silliness. The Portuguese Man O' War (Physalia physalis), also known as the Portuguese Man-Of-War, Man-Of-War, or Bluebottle, is a jellyfish-like marine cnidarian of the family Physaliidae. Its venomous tentacles can deliver a powerful sting. Despite its outward appearance, the Man o' War is not a jellyfish but a siphonophore, which differs from jellyfish in that it is not actually a single organism, but a colonial organism made up of many minute individuals called zooids.
