ORLANDO, Fla.- A manatee was returned to the St. Johns River in Blue Spring State Park Wednesday morning, after rehabilitating at SeaWorld Orlando for the last year.

"Slip" was brought to SeaWorld Orlando on January 4, 2012, after being rescued from Crescent Lake near Palatka, due to symptoms he suffered from cold stress. After he was medically cleared for Wednesday's return, the park's Animal Rescue Team transported the 21-year-old manatee to Blue Spring State Park, an area well-known for its manatee population.

Slip's health was evaluated upon arrival at the park by SeaWorld animal experts and Sea2Shore Alliance. The 1,100-pound manatee was then carried by more than a dozen people into the spring, where a group of manatees were seen swimming nearby.

If you see injured marine animal, you can help by calling the FWC hotline at 1-888-404-3922 or by dialing *FWC on a cellular device.
