What is bryozoan
Freshwater bryozoans are microscopic aquatic invertebrates that live in colonies that can form into jelly-like clumps, and are often found attached to docks or sticks. Bryozoan colonies can be as big as one foot (30 centimeters) in diameter. The base of each tiny bryozoan is attached to a surface. Its body has an outer sleeve-like structure ...Freshwater environments are fragmented and heterogeneous in space and time. Long term persistence thus necessitates at least occasional dispersal of aquatic organisms to locate suitable habitats. However, the insubstantial movements of many require zoochory—hitchhiking a ride with more mobile animals. We review evidence for waterbird-mediated zoochory of freshwater bryozoans, a group that ...
