Floating colonial hydrozoan - detail of dactylozooids
Porpita is a colonial hydrozoan which lives floating on the sea surface. The polyps are arranged concentrically on the lower surface of a hard, chitinous central disk. There is a large central polyp (gastrozooid) around of which are arranged numerous gastro-gonozoids, polyps responsible for food intake and production of jellyfish. The dactilozooids are the polyps responsible for capturing food and defense, being located more externally.
One type of larva typical of bryozoans, cyphonauts spend weeks in the water column until settling on a substrate such as rocks or algae, undergoing metamorphosis into the adult form and creating a new colony.
