A koala can give four thumbs up when they are really impressed.
This photo shows quite clearly that koalas have two thumbs on their front paws. This means they have an excellent grasp of the situation when climbing.
I was tempted not to post this one because he looks so like a cuddly toy, but he’s real!
This image shot with the Sony 135mm GM lens on a Sony A1, at ISO 100 f/1.8 1/250.
