Northern Glass Frog, El Valle, PanamaAlso known as the Feischmann’s glass frog, these guys are known for their translucent skin across the torso area. Their natural defense when threatened is to freeze, making them accommodating subjects — if you can find one. I found this one while walking the grounds of my bungalow after dark in the Panamanian town of El Valle. Nikon D810 with Nikkor 105mm macro lens, ISO 250, f/16 at 1/250th of a second, two Nikkor SB-900 flash units.
