Pyrosomes, genus Pyrosoma, are free-floating colonial tunicates that usually live in the upper layers of the open ocean in warm seas, although some may be found at greater depths.

Freshwater bryozoans attach primarily to leaves, stems, and tree roots in shallow water. Marine bryozoans have a wide range of habitats, from coastal areas to great ocean depths, but are most common just below the tidemarks. Bryozoans feed by capturing plankton with their tentacles. All bryozoans are colonial except one genus, Monobryozon. Thus, bryozoans typically form sessile colonies that live in marine and freshwater environments, and consist of individual zooids that are about 0.5 mm (0.02 in.) long.
