A rat snake eating a whiptail lizard in Corcovado National Park on the Osa Peninsula in Costa Rica.

This was a pretty good fight for a while. At one point the lizard even made a nice move and had the snake in its grip. Eventually, however, the snake was too much for the lizard to handle. After about a ten minute struggle, the snake swallowed the lizard whole in a couple of seconds. This was taken in Corcovado National Park on the Osa Peninsula in southwest Costa Rica.
