The modern Bryozoa collection includes the aquatic animal phyla of the Bryozoa and Entoprocta.
Bryozoans and entoprocts are filter feeders, meaning they sieve plankton from the water using a ring of hairy tentacles known as a ciliated lophophore.
Bryozoa are microscopic colonial aquatic invertebrates, often mistaken for algae or corals, and are also known as Ectoprocta, moss animals or sea mats, and formerly called Polyzoa. The colonies are made up of box-like individuals called zooids.
We know of more than 6,000 recent (living) species. While they are mainly found in marine environments, a small group of approximately 100 species are found in freshwater.
Entoprocta, also known as Kamptozoa, goblet worms or nodding animals, are microscopic aquatic invertebrates. We know of approximately 170 species that live mostly in coastal marine environments.
