The DEP provides information on distribution to the Maryland Department of Natural Resources Natural Heritage Program. Mollusks are thought to be made up of hard calcium carbonate, which is found on their hard shell. Both zebra and quagga mussels starve, suffocate, and crowd out native species, which has led to the decline of native species. They can live in a wide range of habitats and reach high densities of up to 10,000 clams per square meter, and when they die, large amounts of ammonia are released which reduces water quality and harms native mussels.
