Are alligators common to see outside of freshwater? See one swim through a Florida lagoon

An American alligator was spotted last week swimming in the Indian River Lagoon near Crab-E-Bill's Indian River Seafood.

While alligators are known for inhabiting freshwater, they are also known to be seen in brackish water, such as the Indian River Lagoon, according to Zack Jud, director of education and exhibits at Florida Oceanographic Society.
