This little frog looked very much like a toad in the family Bufonidae, but it's classified in the small family Scaphiophrynidae instead. Our guide Mary noticed it hopping across the grass in the morning while the rest of us were admiring chameleons in the trees. My sister, also named Mary, took the second photo above, which shows how well camouflaged this frog is against the decomposing leaf litter.

Here is a list of all the reptiles and frogs I saw on this trip to Madagascar.
