The term "genus Dreissena" specifically refers to a group of small freshwater mussels known for their invasive nature. They are characterized by their ability to attach firmly to surfaces and their rapid reproduction rates. Think of them as the uninvited guests at a party who take over the whole place. The most well-known member is the zebra mussel. They cause ecological and economic harm by clogging pipes and outcompeting native species. Control and prevention are critical challenges.
