Definition: A genus of large oceanic Siphonophora which includes the Portuguese man-of-war.

Some of the zooids have very long tentacles; some have a mouth and digest food; others produce gonophores. The American species (Physalia arethusa) is brilliantly colored, the float being pink or purple, and bright blue; the zooids blue. It is noted for its virulent stinging powers, as well as for its beautiful colors, graceful motions, and its ability to sail to windward.
