Bryozoans feed on plankton and bacteria by sweeping the surrounding water with their lophophore. They are mainly eaten by nudibranchs (sea slugs) and sea spiders.

Are bryozoans filter feeders?

Bryozoa(Polyzoa/ Ectoprocta/ moss animals) are filter feeders that sieve food particles out of the water using a retractable lophophore, a "crown" of tentacles lined with cilia. Bryozoan colonies are called zooids.

How do Ectoprocts eat?

Their colonies are attached to small species of marine algae (AL-jee) and on the shells of mussels and other mollusks. Diet: They eat bits of algae floating in the water.
