female frog found. Male in captivity was thought to be last of their species for past 10 years.

Romeo the Frog Finds His Juliet. Their Courtship May Save a Species.
The lonely male in a Bolivian museum was thought to be the last Sehuencas water frog, but an expedition has found him a potential mate.

Romeo is a Sehuencas water frog, once thought to be the last one on the planet. He lives alone in a tank at the Museo de Historia Natural Alcide d’Orbigny in Bolivia.

A deadly fungal disease threatens his species and other frogs in the cloud forest where he was found a decade ago. When researchers brought him to the museum’s conservation breeding center, they expected to find another frog he could mate with and save the species from extinction. But they searched stream after stream, and nothing.

Romeo, called the “World’s Loneliest Frog,” started sharing his feelings on Twitter. Things got desperate.

He needed a match before he croaked, so last year conservation groups partnered to create a Match.com profile for him. People related to Romeo’s romantic struggles, and on Valentine’s Day last year, the company and his fans raised $25,000 to send an expedition team out to the cloud forest to find his Juliet.

Well, Juliet has been found, and Romeo soon will be a bachelor no more. From this story of star-crossed science and love, conservationists have great hopes. If all goes well when the two meet, their offspring will return to the wild. From there, time will tell if their habitat is preserved, the frogs avoid disease and their legacy continues.
