The Portuguese man o' war isn't actually a jellyfish but a siphonophore, made up of a colony of tiny specialized animals called hydroids. They serve various functions such as feeding, defense, & reproduction. They have no propulsion system & depend on currents & wind for mobility in warm tropical & subtropical waters worldwide. Interesting NatGeo article. #sea #ocean #myt
The Portuguese Man o’ War is not one animal, but is actually comprised of colonies of invertebrate, jelly-like marine animals of the family: Physaliidae glomming together. These pelagic hydroids (or hydrozoans) colonize and are infamous for their very painful, powerful sting.
