Here's why:
* Saltwater habitat: Sharks are saltwater fish, and the Great Lakes are freshwater.
* Lack of connection to the ocean: The Great Lakes are landlocked and have no direct connection to the ocean, preventing sharks from migrating there.
However, there have been rare instances of sharks being found in the Great Lakes, but these are typically due to:
* Accidental release: Someone might have caught a shark in the ocean and then released it in the Great Lakes.
* Misidentification: Sometimes, other fish like lake sturgeon or muskellunge can be mistaken for sharks due to their size or appearance.
So, while it's possible to see a shark in the Great Lakes, it's highly unlikely and definitely not a common occurrence.
