Common Name: Perez’s Snouted Frog
Scientific Name: Edalorhina perezi
Family: Leptodactylidae – Southern Frog family
Location: Brazil, Colombia, Ecuador, and Peru
Size: 0.9 – 1.4 inches (24 – 37 mm)

The Perez’s Snouted Frog blends into the leaf litter on the floor of the Amazonian lowlands of the east Andes.

During the mating season, male calls out from the forest floor to attract the females. Once the female shows up, the male grasps her from behind and around the armpits. This can last up to six days. Then, the female secretes a material that the male whips up into a foam nest. The nests are made at the holes of roots in fallen trees. The female lays between up to 40 eggs in the nest. The pair creates multiple nests. Once the eggs hatch, the tadpoles develop in the nests for 4 – 5 days until they become small froglets.
