“Treefrog Pool Party”

Taken by Brandon Güell in the forests of Costa Rica, this image shows a large crowd of male gliding treefrogs calling out for females to breed with. These large-scale breeding events only occur a few times in the year and only in certain isolated locations. After the females arrive at dawn to mate with their eligible bachelors, they’ll lay up to 200 eggs each, creating giant masses of life that will eventually fall into the water as tadpoles and continue development.
This is a highly commended selection in the “Behavior: Amphibians and Reptiles” category.
