Santra, Yoga Bear, Ähtäri ZOO, Finland

"Then she put up her left leg and put it straight with her hands and held it with her left hand for a bit. Then she lifted the other leg, straightened it and held it with her right hand for around two minutes and then had a little rest and then all over again. It was exactly the same as when you see people do yoga; easy, slow, focused and calm. She looked pretty into it, a really straight face, no looking around just very serious and calm and kept her eyes slightly opened and focused."
Paul Harvey, a Bristol-based yoga teacher and trainer, said Santra was indeed practising the ancient Indian discipline.
"She looks like quite a lonely bear," he said. "Perhaps she's doing yoga to keep herself sane." Harvey, who has taught yoga for 35 years, identified a number of posture variations in Penca's pictures. "The first is spread legs, holding big toes or feet – and she's doing a pretty good job with claws," he said. "The second is the same posture, with chanting. The third is a one leg variation, the fourth a variation with the other leg. The fifth is a seated head-to-foot posture. Six is a single raised leg stretch and seven is a seated, spread-legs forward bend."
