Leptodactylus macrosternum
—
Miranda’s White-lipped Frog
Also known as:
Lesser Foamfrog

The lodge at our last stop in the Pantanal sat just above a small river, giving me the opportunity to poke around for frogs (while avoiding all the caimans and potential jaguars). This was the most standard-jumping-frog-esque of the various species I saw there.
Here is a (fairly short) list of all the reptiles and frogs I saw on this trip to the Pantanal in Brazil.

Here's a somewhat bigger one from the next night.
