Porpita Porpita


"Porpita porpita has a small disc like body and floats freely in the water column. Related to the jellyfish, this species measures just one inch in diameter." "It isn't even a single organism, but a colony! The central disc is reinforced with a chitin-like material and is chambered in cross-section; filled with gas, it keeps Porpita afloat, for these are pelagic creatures. The "tentacles" of Porpita are in fact individual zooids, each of which is specialized for a particular function, such as digestion, prey capture, or reproduction." Link.
