Oklahoma City Zoo

Two elephants living at Hope Elephants rehabilitation center in Maine will be sent back to a sanctuary in Oklahoma in the wake of the crushing death of their caretaker.

Police say veterinarian James Laurita died Tuesday in the animals' barn in Hope when one of the elephants apparently stepped on him.

The struggling theme park chain SeaWorld announced plans today to enlarge and improve the killer whale tanks at three of its parks.

The renovations will begin at the San Diego SeaWorld in 2015, where the total water volume in the killer whale environment will double to 10 million gallons and include a “fast water current” for the whales to swim against.

Tulsa Zoo

The Tulsa Zoo has had to put down a 21-year-old giraffe who had a broken bone in his right, front foot.

Zoo officials said Sunday that Samburu, also known as Sam, died on Saturday. He was born at the zoo in 1992.

The zoo says Sam lived longer than average for a male giraffe cared for by humans. He suffered from osteoarthritis.
