GEORGE TOWN, Cayman Islands (AP) -- A turtle farm in the Cayman Islands says it is freeing a roughly 60-year-old turtle to celebrate British Queen Elizabeth's 60 years on the throne.

Officials with the Cayman Turtle Farm say that the creature known as "Sir Thomas Turtleton" weighs more than 600 pounds (272 kilograms) and has been used to breed for more than 30 years.

The plan is to release it on Saturday in North Sound, the largest protected bay on Grand Cayman Island. Then scientists will track it by satellite.
