Note: At the well site, in the split of a fallen (heliconia-like plant) leaf there is a pile of spit- like bubbles teeming with little tadpoles. Darker dorsal area, speckled head, very small. What type of frog is this? Bubble nest ~5.5" long, single tadpole, 5cm Rogui says: some Leptodactylids build foam nests like this.
