It looks like we’ve lost another one. The weird and unusual Chile Darwin’s frog (Rhinoderma rufum), whose tadpoles grew inside the vocal sacs of adult males, appears to be extinct: a four-year quest failed to turn up any evidence that the species still exists. The frogs were last seen in 1980. As you might guess [...]

A new study finds that frogs, toads, salamanders and other amphibians in the U.S. are dying off so quickly that they could disappear from half of their habitats in the next 20 years. For some of the more endangered species, they could lose half of their habitats in as little as six years. The nine-year [...]

A deadly but critically endangered snake, one of the world’s rarest birds and a heavily guarded flower are among the endangered species in the news this week. A New Snake with a Sad Story: A gorgeous but extremely dangerous new snake species has been discovered in Honduras. The new palm pit viper has been named [...]

The last three males of an all-but-extinct fish species would really, really, really like to meet a female. Once upon a time the Mangarahara cichlid (Ptychochromis insolitus) lived in a single habitat: a river in Madagascar from which the species gets its name. That river has now been dammed and the habitat has dried up. [...]

Thirteen years, 1,500 infrared cameras, hundreds of catnip-baited hair traps and an almost incalculable number of hours in the field have confirmed what scientists have long feared: the Formosan clouded leopard (Neofelis nebulosa brachyura) is in all likelihood extinct. The subspecies, endemic to Taiwan, was wiped out by poaching, trade in its pelts during the [...]

Fan Peng-Fei of China’s Dali University was worried the first time he entered the forest habitat of the critically endangered cao vit gibbon (Nomascus nasutus). The isolated forest, skirting the China–Vietnam border, had been heavily degraded by years of agricultural development, firewood collection and charcoal production. What little forest remained provided poor habitat for the [...]

Poaching, habitat loss, inbreeding and hybridization. These are just a few of the threats faced by many wild feline species around the globe. Here are six of the world’s most endangered feline species and subspecies—some of which may not survive into the next century. 1. Amur leopards Let’s start with the good news: The population [...]

Primates that spend their entire lives in trees tend not to survive after those trees are cut down. Sadly, that’s what’s happening in northeast India, where the forest habitats for one of the world’s rarest apes are rapidly disappearing. The western hoolock gibbon (Hoolock hoolock) has lost an estimated 90 percent of its population over [...]

The population of critically endangered yellow-crested cockatoos (Cacatua sulphurea) in the Indonesian province of West Nusa Tenggara has reached an all-time low of 107 individual birds, according to a recent report from The Jakarta Post. The cockatoos are protected by international and Indonesian law, but they are also highly valued in the illegal pet trade, [...]

A South African butterfly species that lepidopterists feared had gone extinct more than a decade ago has been rediscovered after a search on Google Earth revealed a habitat much like the insect’s former home. That tip refocused a stalled search for the lost species that had not been seen since the mid-1990s. The Waterberg copper [...]
