These small frogs looked like typical poison frogs, which tend to walk or make short little hops in the manner of toads. But Silverstoneia nubicola isn't called "Rocket Frog" for nothing -- they can jump much further than you would expect from their size and shape.

Adult males of this species carry around the tadpoles on their backs until they turn into little froglets. The second photo here shows an adult male with a few little tadpoles on its back.

Here is a complete list of the species we found on this GreenTracks trip.

In 2006 this species was reclassified from Colestethus nubicola in a paper from the American Museum of Natural History by Grant, Frost, Caldwell, et al. Thanks to André Schreiber for telling me about this reclassification.
