Close up with a Black Headed Calico Snake, a harmless mimic of the Hemphrich’s Coralsnake which also lives in the area. Found a couple of years ago in Peru.

These three-striped rocket Frogs are small ground-living animals that are relatively common near streams, wandering through the rainforest floor. They can quickly disappear into leaf litter when spotted. We saw this one in Peru a couple of years ago.

The least likely thing we could have seen in Guatemala – The Torre de Guatel Arboreal Alligator Lizard. Spotted by the laser eyes of Jake Scott, moments after a discussion about how impossible this search was going to be.

Switak’s Banded Gecko that we found in Baja California Sur, Mexico. These are closely related to the Western Banded Geckos we’re all familiar with here in Arizona, with some notable differences. The most obvious being its larger size, this one about the size of a small mouse. When seen in this boulder field, they hop from rock to rock and disappear (or try to, anyway) or wag their tails in a defensive display.

One of the many large treefrogs one can find in the understory of the Peruvian Amazon on a night hike.

One of many Common South American Toads on the floor of the Amazon rainforest, each one a bit different in color, pattern, and even shape.

Central Baja California Banded Rock Lizard from … central Baja California, in the rocks.
