The American Alligators arrived at the Great Lakes Aquarium from a facility called Crocodile Encounters in Angleton, Texas and will be added to the Aquarium's Origins exhibit.

According to a press release:

The 1.5 year old gators were born in the spring of 2016. During prehistoric times reptiles similar to alligators were found in what is now the Great Lakes region. Their fossils are often discovered in Midwestern states. They are on loan for one year at which time Great Lakes Aquarium can request to renew the loan.

The exhibit can be found on the second floor of the Aquarium. I think it's pretty cool that the Aquarium now has gators, because it's something you wouldn't find in the Northland. The Aquarium opens daily from 10am-6pm and is located at 353 Harbor Drive.
