That's an orangutan hand. We are a little similar, ok, we are less hairy :) Look how lovely nails they've got. This photo was taken in Borneo and that's the hand of Mario, an orangutan who came close to our boat to say goodbye. He was the most curious of all I've seen. Maybe because he was in his teens and that's the rebel age.
Well, they are absolutely amazing animals! I'm totally in love with them <3
