The Effects of Translucency on Frogs

The translucency of the glass frog doesn't actually change the color of the frog very much. Instead what changes is the amount of light that is allowed to pass through the frog and specifically parts of the frog such as the outlines of the toes and the legs. The transparency of these frogs did help them blend in with the background especially when they're on something like a leaf, it will allow light to pass through their bodies  at the edges where their legs are meeting the surface. They found ecologically that this level of transparency did increase survival so the frogs that let more light through their skin got preyed on by birds less.
