Chillaxin' chimps: 17 research apes enjoy their golden years

Paul (back), 45, loves the ladies and can sometimes become very jealous of the other males in his group. He only has one leg, but you wouldn't know it when you see him chasing after one of the girls or chasing one of the other boys away. Libby (front), 47, has always been a very curious chimpanzee, wanting to check out every corner of her enclosure. She loves to receive presents or any type of surprise. Libby puts up with the attentions of the males in her group, but dont be fooled, she's in charge.
