Thamnocenchris aurifer (now Bothriechis aurifer) consuming Agalychnis moreletii
The Guatemalan pit viper and Morelet's treefrog share virtually the same habitat (southern Mexico through Guatemala), and both have suffered from habitat loss.
However, the Morelet's treefrog (like almost every treefrog species in the area) has been hit hard by the transmissible fungus, chytridiomycosis, and is now critically endangered. Approximately 80% of the already-small population is expected to die off in the next few years if there's no way found to halt the progression of this disease.
