Illusion, right, a 978 pound manatee is shown in this photo provided by the Cincinnati Zoo & Botanical Garden, Monday, Sept. 17, 2011, at the zoo in Cincinnati. Brought to the zoo last year after being injured by a boat propeller, Illusion has been rehabilitated and will be returned to Florida Nov. 9. She will remain on exhibit at the zoo until Nov. 8. The zoo says the manatee is the eighth to be rehabilitated at the zoo under the U.S. Fish and Wildlife Service rescue and release program. (AP Photo/Ernest Coleman/Cincinnati Zoo & Botanical Garden)
