are there alligators in saltwater
Rating Newest Oldest. Best Answer: Most species of CROCODILE have glands in their mouths to expel salt from their systems. Alligators (remember, folks, there's 20-some-odd species of croc, only two species of true alligator) lack these glands.Alligators spend most of their time in fresh water, but yes, if you're referring to the ICW through Fl, especially the Indian River Lagoon System, alligators ARE in brackish water a LOT.However, they do need to retreat to fresh water on a regular basis to rinse the salt out of their system.lligators spend most of their time in fresh water, but yes, if you're referring to the ICW through Fl, especially the Indian River Lagoon System, alligators ARE in brackish water a LOT.
