Sea Turtle Story

I heard an interesting story on the radio this week. There is only one specialized hospital in the world that studies sea turtles.
I think it is in Key West, USA. A large sea turtle swam up to the dock of this hospital, walked up the plank and entered the emergency room. It is the only known case where a turtle checked himself into a hospital. The turtle had a serious sea turtle disease which is now being treated by the veterinarians there.
