A female zebra mussel begins to reproduce within 6–7 weeks of settling. [17] An adult female zebra mussel can produce 30,000 to 40,000 eggs in each reproductive cycle, and over 1 million each year. [18] Free-swimming microscopic larvae, called veligers, drift in the water for several weeks and then settle onto any hard surface they can find ...
A mussel (genus Mytilus), attached to a rock by its byssus Illustration of the byssus of Dreissena polymorpha, the freshwater zebra mussel. A byssus (/ ˈ b ɪ s ə s /) is a bundle of filaments secreted by many species of bivalve mollusc that function to attach the mollusc to a solid surface.
The most common types of dreissenids are Dreissena polymorpha (Zebra mussel) and Dreissena rostriformis (Quagga mussel). [14] These mussels damage both ecological systems and human infrastructure. In North America, biofouling caused by dreissenids created 267 million dollars’ worth of damage between 1989 and 2004. [ 14 ]
The zebra mussels can use up all the food in the vicinity and deplete the oxygen, and may also consume the native mussels' larvae and sperm, preventing reproduction. Deposits of waste products degrade the habitat. [7] Other invasive species include the Asian clam (Corbicula fluminea), which competes with the native mussel and consumes its sperm ...
The quagga mussel resembles the zebra mussel, just as its namesake (quagga) resembles the zebra. The quagga mussel shell can be distinguished from the zebra mussel shell because it is paler toward the end of the hinge. It is also slightly larger than the zebra mussel, about 20 mm (0.8 in) wide, roughly about the size of an adult human's thumbnail.

The invasion of the Zebra mussel Dreissena polymorpha, (which the U.S. Fish and Wildlife Service trying to control) is one of the biggest threats to the survival of the winged mapleleaf. The Zebra mussel is an extremely invasive species and in 2000 the Zebra mussel began being a problem in the St. Croix River.
Mytilopsis sallei, the black-striped mussel, is a small marine bivalve mollusc in the family Dreissenidae, the false mussels. It is closely related and ecologically similar to the zebra mussel, Dreissena polymorpha. It is also considered as highly invasive species.
