Common Whipsnake (Chironius exoletus)
Our last hike in the Peruvian rainforest started at the Santa Cruz field station and ended up down by the river where we would hop on a speedboat for Iquitos. I was hiking down with Pat Bartlett and Jake Scott. Jake had gone a little ways ahead while Pat and I had paused to photograph a little toad or butterfly or something cool. He yelled something along the lines of "snake!" and in a moment we caught up to him. He was holding this very long, very agitated Chironius. These snakes have a nasty reputation, so our hopes of getting a decent photo seemed rather dim. But after a few minutes of trying to settle it down, it adopted this defensive posture in the middle of the trail and deigned to allow a few photos. It also bit me several times, but very mildly; its bite didn't even break my skin. This was a species that neither Jake nor I had yet seen, so it was a nice little going-away present. (Pat has visited the Peruvian rainforest several times so this was just an old friend to her.)

Here is a complete list of the herps I saw in the wild on my 2013 MT Amazon Expeditions trip.
