Dreissena Polymorpha, commonly called the Zebra Mussel, is a small freshwater bivalve known for its distinctive black and white striped shell. This invasive species has caused devastating effects in aquatic ecosystems, including clogging water intake pipes, outcompeting native species, and altering nutrient cycles. Synonyms for Dreissena Polymorpha include the Zebra Mussel, the European Zebra Mussel, and the Polish Mussel. Despite its small size, this mollusk has had a significant impact on freshwater systems worldwide. Efforts to control its spread have included physical and chemical treatments, as well as biological control measures such as introducing predatory fish to control populations.
