A frog believed to be the last of his kind in the world has been granted a reprieve from solitude. Romeo, known as the world’s loneliest frog, has spent 10 years in isolation at an aquarium in Bolivia. Scientists say they have found him a Juliet after an expedition to a remote Bolivian cloud forest. Five Sehuencas water frogs found in a stream were captured, with the goal of breeding and re-introducing the amphibians back into the wild. The five frogs – three males and two females – are the first Seheuncas water frogs to be seen in the wild for a decade, despite previous searches in the Bolivian wilderness. Romeo was collected 10 years ago when biologists knew the species was in trouble, but was not expected to remain alone for so long. He attracted international attention a year ago over his search for a mate, and was even given a dating profile.
