Biddy ( same as above) these are nice shots- she has her mouth closed properly- Nowdays she often has her lower lip hanging down showing the pink. I believe there may be some medical explanation for this condition for this as it happens in quite a lot of older primates, but not others.
She also did have her lower lip dropped a bit for long periods of time. She's quite placid and was happy to pose for photo's she even sat up so I could get a better shot!
