Where do zebra mussels grow?
Zebra mussels (Dreissena polymorpha) are small, freshwater, bivalve shellfish that were likely brought to the U.S. as stowaways in the ballast water of ships. They are native to the Caspian and Black Seas south of Russia and Ukraine, and have since become widespread in both Europe and the U.S.
How did zebra mussels spread?
Zebra mussels spread in a few ways: Their larvae, also called veligers, spread within bodies of water in the form of plankton. The microscopic veligers spread between bodies of water by live wells, bait buckets, bilge water, dive gear, waterfowl, and anything else that moves from one body of water to another.
Where do zebra mussels invade?
Zebra mussels reached North America in the mid-1980s in the ballast water of a ship. They rapidly became established in the Great Lakes and the waters draining them.

How did zebra mussels get to California?
The zebra mussel (Dreissena polymorpha) has finally established a population in California. A native of Europe, the zebra mussel lives in freshwater lakes and streams, and was likely transported to the United States in the ballast water of a trans-Atlantic freighter.
How do mussels move?
Mussels spend most of their life in a small area of the lake or stream bed that they inhabit. However, they do have the ability to move around with the use of their muscular foot. Mussels insert their “foot” into the sand or gravel and pull themselves forward, inching their way along the bottom.
How do mussels reproduce?
Female mussels fertilize their eggs with sperm from a male and develop larvae called “glochidia”. Once mature, females may release their glochidia into the water or even attract a fish to swim close with a lure.
What are mussels made of?
The shell is composed of calcium carbonate and protein. The often white shiny layer seen inside the shell is called the nacre, or “mother of pearl.” The outer layer or periostracum is made of protein and serves mainly to protect the shell.
What provinces have zebra mussels?

Did zebra mussels clean up Lake Erie?
By the autumn of 1989 zebra mussels had colonized the surfaces of nearly every firm object in Lake Erie. Colonies also have been discovered throughout Lake Ontario and in Lake Michigan’s Green Bay.
Do zebra mussels make pearls?
Mussels, like their salt water counterparts, oysters, create pearls. When a bit of foreign matter lodges in a mussel, the animal uses its nacre—the same material it uses for shell building, to reduce the irritation by coating the offending object. The results are luminous, glamorous and can be very rare.
How did the zebra mussels could spread so fast on 40 of us and two Canadian provinces?
Zebra Mussels entered the Great Lakes in the late 1980s through ballast water discharged from ships. Since then, they have spread through much of eastern Canada and the United States.
Are there zebra mussels in the Atlantic Ocean?
