Green Jeans Frog

Green Jeans Frog

This species of poison-dart frog (Dendrobates granuliferus) is sympatric with the species traditionally called the “Blue Jeans Frog” (Dendrobates pumilio), meaning the two are essentially the same. This particular variation, with granularity of the skin and jade-colored limbs, is found in the southwest lowlands of Costa Rica, where there is a population in the Golfo Dulce region. The specimen here was photographed near La Tarde. Since I’m not sure what the common name for this amphibian might be, I’ve decided “Green Jeans Frog” is as good a moniker as any. “Red Hoodie Frog” might be even better!

Parrot Snake

The Parrot Snake (Leptophis ahaetulla) in the above photo is furious because it just lost an epic battle with its lunch. Wrestling in the mud of the rainforest floor near Serena, the unidentified frog (possibly a member of the genus Phrynohyas) kept scrambling, and the writhing reptile just couldn’t get a solid grip. After several minutes, the amphibian finally slipped free and made a break for it!

The frog’s body appears to swell and secrete a mucus that aids in its escape.

Golfo Dulce Poison Frog

Golfo Dulce Poison Frog

The author of my fiercely scientific guidebook about amphibians and reptiles in Costa Rica doesn’t believe in common names. “Poison Frogs of the Genus Phyllobates” is about as close to a vernacular description as I can find in the text for this shiny little gem. This particular specimen (Phyllobates vittatus) was found in a tiny mud cave in the Corcovado National Park by expert guide, Nito. The species is endemic to the area near the Osa Peninsula and the Golfo Dulce, and so I’ve assigned it the not-very-scientific appellation “Golfo Dulce Poison Frog.”
