Presence of Freshwater Sponges in Minnesota Lakes Sparks Research
It isn't necessary to go to the ocean to find a sponge. In the sunlight dappled waters of a Minnesota stream or lake, a freshwater sponge might be thriving.
The idea of freshwater sponges living in lakes and streams in Minnesota may come as a surprise to many, but these simplest-of-all animals have been filtering the waters of the northland for millennia and their presence has often been overlooked. What makes the study of these animals significant is their possible connection to the health of freshwater ecosystems in the state.
