A frog named Romeo, was once called the loneliest frog on earth and was long thought to be the only Sehuencas water frog in existence. He got international attention last year, when scientists created an online dating profile for him to help find a mate. It worked. Scientists found four other water frogs in the wild.
Frogs can breed from between two and three years old. They often return to the pond where they were spawned, and males attract females by croaking. Breeding involves the male attaching himself to the back of the female by grasping her under the forelegs, where he stays until she lays her eggs.
