Hundreds of Tiny Frogs Released on a Mission to Save Their Species

These tiny, vibrant frogs are on a mission to help save their species. Scientists released hundreds of harlequin frogs into the wilds of Panama in hopes of collecting valuable data. Critically endangered, their population has declined by more than 80 percent over the last three generations largely due to a deadly disease caused by a fungus called chytrid fungus. 500 frogs were given unique markings visible under UV light, and over the next few months, scientists will track where they go and if they survive. Researchers hope that they can map areas where the amphibians are more susceptible to the deadly fungus, and find refuges where the frogs can thrive once again, or even create artifical safe areas of their own.

The train in front of me is a beauty: an old-fashioned red, black and yellow locomotive that looks wonderfully at home in the Central American sunshine. Inside, its wood-panelled, lamp-lit coaches feel like they belong to a classier age of rail travel.
