Dozens of frogs, fish, orchids and other species — many unseen for decades — may no longer exist due to humanity’s destructive effects on the planet.

Scientists have rediscovered the endangered Mindo glassfrog, which hasn’t been seen in decades. And it’s just one of many remarkable species they’ve found in an at-risk habitat.

The Mindo harlequin toad, last seen in Ecuador in 1989, was feared a victim of the amphibian-killing chytrid fungus. Have other lost species survived, too?

Our desire for the companionship of exotic pets from around the world has fueled the spread of disease.

Diseases can cause animal populations to decline or even go extinct. And they’re often worsened by environmental threats caused by people.

Well, more specifically their footprints. New research finds that elephants create foot-shaped habitats for breeding frogs as they travel through the forest in Myanmar.

After decades of rumors and searches, the existence of a two-foot-long amphibian called “the reticulated siren” has finally been confirmed.
