The zebra mussel (Dreissena polymorpha) is a small freshwater mussel. The species originates from the lakes of southern Russia and Ukraine, [ 3 ] but has been accidentally introduced to numerous other areas and has become an invasive species in many countries worldwide. Since the 1980s, the species has invaded the Great Lakes, Hudson River ...
The incorporation of the round goby into native foodwebs, coupled with the goby's ability to consume large numbers of invasive mussels (zebra and quagga), may result in greater bioaccumulation of toxins such as PCBs higher in the food chain, since these mussels filter-feed and are known to accumulate persistent contaminants.
The shells of species of mussels in this family range from 20 to 40 mm in their maximum dimension, and about half as wide across. The shell outline is bent, with one margin usually somewhat incurved, and the other strongly curved outwardly. The shell is opaque and robust; in coloration it is yellowish, brownish or greyish, often with light-and-dark stripes.
The quagga mussel shell is generally black, yellow, and/or zig-zagged. However, a large range of shell morphologies is seen, including a distinct morph in Lake Erie that is pale or completely white. The shell has a rounded carina and a convex ventral side. The quagga mussel resembles the zebra mussel, just as its namesake (quagga) resembles the zebra. The quagga mussel shell can be ...
Exotic species Zebra mussels are present in C. monodonta ’s current range and threaten all native mussels through direct fouling of their shells. Once attached to a live, native mussel shell, zebra mussels can impede locomotion (vertical and lateral), disrupt normal valve moments, deform valve margins, and deplete local food resources. [ 4]

Epioblasma triquetra, common name the snuffbox mussel, is a species of freshwater mussel, a mollusk in the family Unionidae. It is native to eastern North America, where it is a listed as an endangered species in both Canada and the United States. [1][2][4]
Dreissenidae are a family of freshwater mollusks considered to be an invasive species found across Eurasia and North America. [14] 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.
