Pennywise, weighing 302 pounds, was deemed healthy and strong enough to return to the wild Wednesday after being treated by Loggerhead Marinelife Center’s veterinary team over the past few months.

The researchers, with others from Honduras, are looking for ways to help reefs survive increased temps caused by global warming. The work could provide a blueprint for working across the Caribbean to share corals.

The turtle was too big to get a CT scan on a human machine, so the team headed to an equine clinic and had the scan performed on equipment designed for horses.

Figuring out what cooling activities the animals enjoy requires a bit of trial and error.
