    Reusens achieved the pictures by putting the frogs on panes of glass and using a twin diffused flash. The flash showcased the natural effect of these translucent animals. After the photo shoot was over, all the amphibians were returned to the wild.

    The frog-loving photographer was able to travel to Costa Rica thanks to a job that requires nature photography. While Reusens was hoping to get a few snaps of the glass frogs, he was unsure about the chances of it actually happening.

    "Glass frogs are difficult to find and collect, due not only to their small size and color, but also because of the extreme areas they sometimes inhabit," Reusens told the Daily Mail U.K. "Glass frogs are often found along streams that are nearly impossible to walk along, let alone collect specimens."

    Thankfully, Reusens was able to find a few of these 20 millimeter-long cuties. The photographer is optimistic that more glass frog species will be discovered as researchers continue to explore previous inaccessible parts of the world.
