Along with Phyllomedusa tomopterna and Phyllomedusa bicolor, this was the third species of monkey frog easily found around the pond at the Santa Cruz field station. Really, it's the place to be for monkey frog lovers (and who in their right mind is not a monkey frog lover?).

Monkey frogs are so named due to their typical locomotion consisting of exaggerated walking, rather than the jumping that sensible people have come to expect from sensible frogs.

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

On my fourth trip to Santa Cruz Forest Reserve, a few of these silly frogs could be found most every night in a couple of plants close to the big pond.

Such odd frogs! When their pupils are dilated they are especially cute, and when their pupils are constricted they look the most like space aliens.
