They are colonial, but the colonies can superficially resemble jellyfish; although they appear to be a single organism, each specimen is actually a colony of Siphonophora. The gonozoids of the man o’ war are the polyps that are responsible for reproduction. Excellent video of Portuguese Man-of-war (Physalia physalis) in open waters by National Geographic Video. The larva formed by the union of an egg and sperm then reproduces asexually by budding or mitotic fission until it achieves its mature form.
