We also propose a framework for homologizing the axes with other siphonophores, and also suggest that the tentacle bearing zooids should be called tentacular palpons. Locomotion is generally passive, driven by wind and current. Like all siphonophores, it is a colonial organism, made up of many smaller units called zooids. UCG Ser UAG Stop Additional support for this view comes from the observation that the regenerative powers of the man-of-war are poor, in contrast to most other jellyfish. The Portuguese man o' war is a highly venomous open ocean predator that superficially resembles a jellyfish but is actually a siphonophore.
