The bottom picture is of a baby aye aye (Daubentonia madagascariensis). In fact the above image is of a baby aye aye called smeagol who was born at Philadelphia Zoo in 2010 http://www.zooborns.com/zooborns/aye-aye/.
Was I fooled! I had thought that the animals in both photos were of the same species -- just at different stages of development. So the top photo is of a fruit bat; the bottom photo is of a baby aye-aye lemur.
