The principal predators of marine bryozoans are sea slugs and sea spiders.1
These organisms are significant enough in the ecology of bryozoans that some species have developed phenotypic plasticity in response to predation pressure. In such cases, the bryozoans can alter the form of newly generated zooids, for example by developing more heavily armored or spined outer coverings to deter these predators.2
