With all the depressing news about the global amphibian die-offs, a bit of good news: Scientists are discovering lots of new species, bringing the total to more than 7,000. In the past 20 years, frogs and other amphibians have been dying in alarming numbers. More than 40 percent of amphibian species are threatened with extinction, according to the most recent IUCN Red List of Threatened Species. The main causes are habitat destruction, climate change, and a sinister new fungal disease called chytridiomycosis. But despite this, or perhaps because of it, there’s been a surge in discoveries of new species in recent years. “Once it became apparent that amphibians were declining, there was a great interest in amphibians,” said biologist David Wake of the University of California, Berkeley, who founded Amphibiaweb, a database to catalog new amphibian species. ”When we started it in 2000, we thought that the age of amphibian discovery was pretty well done,” said Wake. But now, about 2.5 new species are added every week. Here are some of our favorites from the most recent rounds of discoveries. Above: Sabin's Glassfrog On July 29, Sabin’s glassfrog (Centrolene sabini) became the 7,000th species on Amphibiaweb.Alessandro Catenazzi, of San Francisco State University, discovered the little frog in the small streams of the Kosnipata valley in Peru, at an elevation of 9,000 feet. They’re called glassfrogs because their skin is transparent, exposing their internal organs and bones. During the cool nights, the males of the new species call out to attract females who come to lay their eggs on leaves above streams. Image: Alessandro Catenazzi

Prince Charles Stream Tree Frog Yes, His Royal Highness has a frog named after him. The Hyloscirtus princecharlesi frog was named in honor of the prince’s efforts to promote tropical rainforest conservation (a pastime that has earned him the nickname the “Frog Prince”). The frog, with its characteristic orange blotches, lives in the cascading streams of cloud forests in Ecuador. It was described as a new species by Luis Coloma, of the Otonga Foundation in Ecuador, and colleagues. Image: Luis Coloma

Splendid Web-Footed Salamander Only a single specimen of the splendid web-footed salamander (Bolitoglossa splendida) has ever been seen. It was found in the remote mountains of Costa Rica, reachable only by several days’ hiking. Eduardo Boza-Oviedo, of the University of Costa Rica, San Pedro, led the discovery. Biologist David Wake, a colleague of Boza-Oviedo, described it as having a glossy black body with “a Heinz tomato-red back and Heinz mustard-yellow spot.” DNA sequencing analysis confirmed it as a new species.

Rhinella inopina Toad The Rhinella inopina toad species lives in the seasonal tropical dry forests of central Brazil. The stern-looking toad has a “robust” body and head wider than it is long, according to a paper by Wilian Vaz-Silva of the Central University of Goiás – Uni-Anhanguerain Brazil and colleagues, who first described the species. It ranges in color from yellowish-cream to brown, sometimes with sparse dark spots. Image: Danusy Lopes Santos

Bolitoglossa guaneae Salamander The little Bolitoglossa guaneae salamander hails from the Cordillera Oriental mountains in Colombia. It was named for the native Guanes people, who have inhabited the same region since 600 B.C. (and were nearly decimated by the Spanish in 1586). It was discovered by Andrés Acosta-Galvis and Doris Gutiérrez-Lamus of the National University of Colombia. Images: Andrés Acosta-Galvis

Yellow Dyer Rainfrog The tangerine-colored yellow dyer rainfrog (Diasporus citrinobapheus) makes its home in the Cordillera Central in Western Panama. Its call sounds like a whistle, and although its bright-colored skin is not poisonous, researchers speculate it might not make the tastiest meal for a predator. It was observed and described by a team led by Andreas Hertz of the Senckenberg Research Institute and Nature Museum in Germany. Image: Andreas Hertz

Matama Moss Salamander Perhaps the world’s tiniest salamander, the Matama moss salamander (Nototriton matama) lives in the mountains bordering Costa Rica and Panama. It spends its days hidden in tendrils of moss. Finding one requires hundreds of hours of searching through vines in the forest, according to biologist David Wake, whose colleague Eduardo Boza-Oviedo reported the new species.

Jackie's Reed Frog The Jackie's reed frog (Hyperolius jackie) was found in Nyungwe National Park in southern Rwanda and described by Maximilian Dehling of the University of Koblenz-Landau in Germany. It has the characteristic transparent skin of a glassfrog, blue-colored bones, and a call that is distinct from other frogs of the same genus. Image: Maximilian Dehling

Yellow-Throated Web-Footed Salamander This little salamander, Bolitoglossa aureogularis, was also discovered by Eduardo Boza-Oviedo and colleagues, in the Cordillera de Talamanca mountain range in Costa Rica. Its body has a golden-tan color, with a bright blast of yellow under its chin — hence its name aureogularis*,* meaning “golden throat.” The species was found among the roots and leaves of bromeliad plants.
