Portuguese man-o’-war is not. It too, like an ant hill or a termite community, is a colony of individual creatures (in this case, small multicellular forms known as zooids), aggregated for a common purpose and variously performing specialized functions. Likewise that very strange thing known as a cellular slime mold, which during one phase of its existence looks and behaves like a garden slug, but at another phase reveals itself to be a fine-tuned team of individual amoebae.
