A rescued green sea turtle has found a new home at a Las Vegas casino.

The 320-pound, turtle named OD (after the boat that found him) was found floating on his side with a collapsed lung, Reuters reported. He is believed to be about 50 years old.

OD has been under the care of a Florida turtle hospital for almost five years. Hospital officials decided the lucky turtle needed a "larger and more stimulating environment."

"He's ready now for a forever home ... where he can live out his life," said Turtle Hospital Manager Bette Zirkelbach.

OD moved to Shark Reef Aquarium, a 1.6 million gallon aquarium. Several other sea turtles already live there.

Because of his collapsed lung (which leaves OD lopsided), he swims with weights attached to his shell, Time reported.

"He can't function in the wild because he floats, the good lung overcompensates and he floats to one side," Zirkelbach said, CBS reported.

FedEx provided OD with free transportation. He was shipped by air in a "specially moisturized and foam padded crate," according to, Time. 

Turtle hospital manager Richie Moretti accompanied OD on the 2,400 mile trip, CBS reported.

"This is going to be lot bigger tank with a lot more excitement," Moretti said. "There's going to be coral, there's going be other turtles and fish, this is going to be a great home."

OD will have to be quarantined for 45 days before he can swim in the large tank with the other sea turtles.

Green sea turtle's life spans are unknown, but they are believed to reach sexual maturity between the ages of 25 and 50-years-old, the Office of Protected Resources reported.

They are the largest of all hard-shell sea turtles, but have a surprisingly small head. Unlike most sea turtles, they eat only plants.

Green sea turtles are considered endangered species, their populations started to decline about 150 years ago.
