Marine ectoprocts live in shallow waters near the coastline to deep-sea bottoms at depths of 26,900 feet (8,200 meters). They are also found on the surfaces of solid objects, including rocks, seashells, seaweed, and wood.

Where are you most likely to see a living bryozoan?

Bryozoans are common and easily found, especially in moderately eutrophic waters with abundant rock or wood substrata. Most species can be found in water less than 1 m deep.

Where are bryozoans found?

Worldwide, bryozoans are found on every continent except Antarctica. Although most bryozoans are marine, one class (Phylactolaemata) lives only in freshwater. About 20 freshwater species occur on our continent. These usually prefer the rather quiet waters of lakes, ponds, and swamps, but some live in streams.
