Fitzingers Rain Frog, El Valle, PanamaThis tiny little guy is called a Fitzinger’s Rain Frog (I’m going to go out on a limb here and say he was discovered by Fitzinger). He was probably no more than an inch in length, but I somehow spotted him while on a hike in El Valle, Panama.Nikon D800 with Nikkor 105mm macro lens, ISO 200, f/25 at 1/60th of a second, two Nikon SB-900 flash units
