What sea creatures are in Niagara Falls?

The Niagara River is host to over 60 species of fish. Furthermore, the waterways near Niagara Falls are home to many different fish species, such as the American eel, largemouth bass, channel catfish, rainbow trout, and lake sturgeon.



Technically, there are no sea creatures in Niagara Falls because it is a freshwater system. However, the Niagara River and the Great Lakes are home to over 60 species of fish. One of the most unique is the American Eel, which is catadromous, meaning it lives in freshwater but migrates to the Sargasso Sea in the Atlantic Ocean to spawn; thus, you are seeing a creature that bridges both worlds. Other prominent residents include the prehistoric Lake Sturgeon, which can grow up to 2 meters long, as well as Rainbow Trout, Chinook Salmon, and various species of Bass. In 2026, conservation efforts have successfully protected these populations, but you won't find dolphins, sharks, or true "sea" life here due to the lack of salinity. The water's powerful flow into Lake Ontario creates a highly oxygenated environment that supports these massive freshwater giants, many of which can actually survive the plunge over the falls.
