Bryozoan “Blobs” in Freshwater Systems
Bryozoans occur in both saltwater and freshwater systems. The UF Museum of Natural History refers to them as “moss animals” (Museum 2018). Its easy to see how they could be confused with tadpole eggs.
Bryozoans are filter feeders. They become evident in the warm summer months. Sometimes they turn green from algal epiphytes. Florida LakeWatch has a nice article on bryozoans on pg 11-12 in their newsletter (vol 40 11-15-07)
