Ranitomeya flavovittata poison frog, PeruWhat is a Ranitomeya flavovittata? This guy, of course. One of the more spectacular little poison dart frogs to be found in the Loreto region of the Peruvian Amazon. I had to get deep within the bromeliad plant with my macro lens to get this shot of the fingernail-sized frog. Nikon D850 with Nikkor 105mm macro lens, ISO 500, f/20 at 1/60th of a second, Nikon SB-900 flash.
