<P> The Atlantic Portuguese man o ' war ( Physalia physalis ) , also known as the man - of - war , or floating terror , is a marine hydrozoan of the family Physaliidae found in the Atlantic Ocean , as well as the Indian and Pacific Oceans . Its venomous long tentacles deliver a painful sting , which on extremely rare occasions has been fatal to humans . Despite its outward appearance , the Portuguese man o ' war is not a true jellyfish but a siphonophore , which , unlike jellyfish , is n't actually single multicellular organism , but a colonial organism made up of specialized individual animals ( of the same species ) called zooids or polyps . These polyps are attached to one another and physiologically integrated , to the extent that they are unable to survive independently , and therefore have to work together and function like an individual animal . </P>
