WATCH: Chicago's 'Chance the Snapper' settles in at new home at St. Augustine Alligator Farm

Jacksonville, FL — An American alligator that's become known as 'Chance the Snapper' has arrived at his new home in St. Augustine.

After being rescued from a lagoon in Humboldt Park in Chicago, 'Chance the Snapper' will live out the rest of his days at the St. Augustine Alligator Farm.

As part of his introduction to his new home, 'Chance the Snapper' was weighed and measured. The park says he's exactly 4-feet long and weighs 18 pounds.

While he appears to be pretty health, we're told 'Chance the Snapper' will be quarantined in his own pool for 90 days as they learn more about his history and whether he carries any diseases. If everything checks out, the plan is to eventually introduce him to other alligators.

St. Augustine Alligator Farm staff believe based on his health and light coloring, he was likely released by someone who may have been keeping him as a pet or he somehow escaped on his own.

It's not believed that 'Chance the Snapper' would have been able to survive a Chicago winter.
