    ☞ It has a large air sac, or float, with a sail-like crest on its upper side. Numerous zooids of different kinds are attached to the under side of the float. 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.
