Portuguese Man-of-War
The Portuguese man-of-war is actually a colony of specialized polyps that all contribute to the well being of the colony by performing specific tasks, such as feeding or providing buoyancy control. The man-of-war has a relatively large, gas-filled bladder that provides flotation for the entire colony. A large collection of feeding polyps suspended from the underside of the float, each with a single, long tentacle, captures and digests food, which is then shared with the entire colony by means of interconnecting digestive cavities. Although the Portuguese man-of-war resembles a jellyfish, it belongs to Class Hydrozoa in the phylum Cnidaria, while true jellyfish belong to Class Scyphozoa in the same phylum.
