Eyelash Viper: Frog Heaven, Sarapiqui, Costa Rica, March 2025 — One of the highlights of a visit to Frog Heaven, for those who are so inclined (and I know it is not everyone) is the snakes they bring out towards the end of your time there. There is nothing quite like a bright yellow Eyelash Viper posed on a branch in the dark of the night. Eyelash because of the pointy scales above the eye. Viper because it is. a pit viper…notice the little heat sensor between the eye and the nostril. Photographed by the light of my Ulanzi Photo Flashlight (not a flash but a handheld led torch). Sony a6700. Tamron 50-400 at 409mm equivalent. Aperture program with my macro modifications. F16 @ 1/40th from my little travel tripod. -1 EV to tame the highlights.
