(Centrolenidae Family) (Hyalinobatrachium sp.)
Amazon rain forest. SE ECUADOR
These frogs spend the day flattened on the underside of leaves such that when viewed backlit against the light their transparency affords them perfect camouflage. From the underside they are completely transparent and their internal organs (heart, spleen, intestines, lungs) and bones can be seen through their skin. They feed mainly at night.
