Floating colonial hydrozoan - medusae
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.
