Glass Frog or Crystal Frog (Hyalinobatrachium pellucidum)
The frog is named for its skin which is translucent to the point that internal organs and surfaces immediately behind the frog can be seen. The reason for this is lack of pigmentation. It is endemic to Ecuador. Its natural habitats are subtropical or tropical moist mountains and rivers. It is threatened mostly by habitat loss, although conservation programs have begun to help save this interesting creature.
This frog is about the size of a fingernail.
