ABSTRACT. Current biogeographical distributions of freshwater sponges (Porifera) and bryozoans (Ectoprocta and Entoprocta) are poorly known in Indiana. Although seemingly ubiquitous in many aquatic communities, neither group has received much notoriety in this state, nor the midwestern United States. In an initial effort to begin the systematic taxonomic distribution of these groups in Indiana, this study identified 2 sponges and 13 bryozoans in northwest Indiana lakes. The recent appearance of the zebra mussel (Dreissena polymorpha) in the Great Lakes has focused new attention on the sessile benthic communities, as significant changes in benthic community structure are ...
