Vienna - Schurli, the giant tortoise, is the oldest inhabitant of the Vienna zoo. But despite his age of more than 100 years, the animal has started a fitness training programme.
The exercise regime is part of a research project conducted by scientists from the zoo and the Hebrew University of Jerusalem to learn about the animal's visual and learning capabilities.
The male Seychelles giant tortoise is not the most animated creature, but when he notices his keeper Roland Halbauer approaching, he knows his training session is about to start.
