What eats freshwater bryozoans?
Predators of marine bryozoans include sea slugs (nudibranchs), fish, sea urchins, pycnogonids, crustaceans, mites and starfish. Freshwater bryozoans are preyed on by snails, insects, and fish. In Thailand, many populations of one freshwater species have been wiped out by an introduced species of snail.

Bryozoans can reproduce sexually or asexually through budding and fission, and individual zooids are hermaphroditic. Statoblasts (Fig. 10.9C), the small, resistant structures of the Ectoprocta that are formed through budding, are important for dispersal and surviving harsh conditions.

Pectinatella magnifica can serve as an intermediate host of Tetracapsuloides bryosalmonae, a myxozoan parasite that causes Proliferative Kidney Disease (PKD) in salmonids (Okamura and Wood 2002). PKD is especially problematic for rainbow trout ( Oncorhynchus mykiss) aquaculture in the western U.S. (Merck 2015).
