There are several things that feed on bryozoans. These animals include fish, insects, snails, mussels, and several other water animals.
Bryozoans are consumers
Where do bryozoans live? Bryozoans live in almost every kind of benthic (sea floor) habitat in the ocean, from the shore to the greatest depths. On sandy beaches (like Virginia Beach) you would be most likely to find bryozoans living on shells, mermaids' purses (skate egg cases) or the molted shells of horseshoe crabs. On rocky shores or reefs colonies encrust seaweeds or the undersides of rocks or corals. On sandy or muddy sea floors rooted bryozoans (like these from Antarctica) can be the most abundant animals present. They are very common on floating plastic trash and on ships' hulls, hitching a free ride for hundreds or thousands of miles. They are also found in fresh water where their colonies are attached to the undersides of rocks as well as submerged wood and the leaves of pondweeds. Some freshwater bryozoans, like Pectinatella, form massive colonies in ponds and reservoirs in late summer and early fall. Other freshwater species form inconspicuous networks like those of Plumatella.
Nudibranchs eat bryozoans
Producers
Arthropoda is the phylum characterized by having an exoskeleton made of chitin. This phylum includes animals such as insects, spiders, and crustaceans.
Depends where you are looking, In the Paleozoic it is generally bryozoans, brachiopods, and crinoids.
Freshwater angelfish can't survive in the ocean. Therefore, they don't live there, and they don't eat there!I'm going to assume that you're referring to marine angelfish. Different species of marine angelfish feed on different things. The species of the genus Genicanthus feed chiefly on zooplankton in the wild, while members of the Centropyge feed on filamentous algae. There are some species that feed on fish eggs, sponges, tunicates, bryozoans, hydrioids, and/or various sessile benthic invertebrates.
usually freshwater.......
The most common term for the study of freshwater and freshwater systems is Limnology!
