Frog fanciness

A recent trip to the Rio Zunac Reserve turned up some beautiful frogs in the genus Pristimantis. This is the largest genus of vertebrates, and its local diversity in our area is staggering. Most of them seem nondescript at first glance, but many of them have bright species-specific “flash colors” on their sides, bellies, or inner thighs. This lovely P. katoptroides photographed  by our forest guard Fausto Recalde is an example. Its inner thighs are an intense indigo blue:

Here is another Pristimantis found on an earlier trip to the forests adjacent to the reserve, which we are raising money to purchase. This one has dramatic yellow stripes on its inner thighs and sides . Juan Pablo says that this is almost certainly a new species!

The eyes can also be very colorful, as in this Pristimantis eriphus found on the same trip as the P. katoptroides:

This is probably the same species, from our Cerro Candelaria Reserve:

Here’s Pristimantis galdi from the Rio Zunac Reserve with green eyes:
