Hidrozoário colonial flutuante, vista aboral - dactilozoóides distendidos
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.
The fire-worms are benthic animals that live under rocks and among other marine organisms; they have white, numerous, and large bristles that may cause skin irritation.
