Have sharks ever been found in the thousand islands of the st lawrence river?

Sharks are not typically found in the Thousand Islands region of the St. Lawrence River, as this freshwater environment is not suitable for most shark species, which prefer saltwater habitats. However, there have been rare instances of bull sharks being spotted in the river, as they are known to tolerate freshwater for limited periods. Overall, such occurrences are extremely uncommon and not representative of the typical marine life in the area.
