The Portuguese Man o' War (Physalia physalis), also known as the blue bubble, blue bottle, man-of-war, or the Portuguese man of war, is a jelly-like, marine invertebrate of the family: Physaliidae, order: Siphonophora, class: Hydrozoa, and Phylum: Cnidaria. The common name comes from a Portuguese war ship type of the 15th and 16th century, the man-of-war (named caravela-portuguesa in Portuguese, caravel), which had triangular sails similar in outline to the bladder of the Portuguese Man O' War.
