Similar to coral, and much like the individual cells in our body, the individual zooids of Siphonophorae are so specialized that they lack the ability to survive on their own. Siphonophorae thus exist at the boundary between colonial and complex multicellular organisms. The Portuguese Man of War is probably the best known example of a Siphonophore, but there are others out there, some of which may well blow your mind.
