13th Annual Smithsonian Magazine Photo Contest Natural World
Mating Red-Eyed Tree Frogs

A male red-eyed tree frog (Agalychnis callidryas) takes a cheeky nap atop a female while he waits for her to lay eggs. This position is called "amplexus," and it puts the male in position to externally fertilize the female's eggs as soon as she has laid them.
