Invasive Species in Lake Michigan
While the native species of Lake Michigan have adapted to the unique conditions of the lake over centuries, the introduction of invasive species has disrupted the delicate balance of the ecosystem.
Sea Lamprey
The “vampire of the Great Lakes,” the sea lamprey is a parasitic eel-like fish that attaches to and feeds on the blood of native fish species, causing significant damage to populations.
Alewives
These small, herring-like fish were introduced unintentionally and have become a dominant species in Lake Michigan, altering the food web and competing with native fish.
Zebra and Quagga Mussels
These tiny, prolific mussels filter nutrients from the water, changing the lake’s ecosystem and affecting the growth and survival of native species.
Pacific Salmon
Introduced to control alewife populations, Pacific salmon have now become an invasive species in Lake Michigan, competing with native fish and disrupting the natural balance.
Other Notable Animals in Lake Michigan
While the native and invasive species garner much attention, Lake Michigan is home to a variety of other fascinating creatures.
Snapping Turtles
These large, powerful turtles are native to the Great Lakes region and can be found in the waters and wetlands of Lake Michigan.
