Frog pattern

I actually managed to get a relatively clear picture through glass of this little guy? girl? during my last visit to the Cleveland Zoo Rainforest exhibit. He was a fascinating blueish-white with dark markings and he smiled at me when I was taking his picture.. :) I want to say he was labelled as an Australian milk toad, but I can't find that designation when I searched the Internet, so maybe I remembered wrong? Will have to check on that the next visit I make to the zoo...

*Later note* turns out the Australian milk toad is actually an Amazon milk frog- the zoo's webpage has a fantastic index of animals with pictures. At least I got the 'A' and the 'milk' part right.. :)
