The death by old age this past weekend of Angalifu, a 44-year-old northern white rhino (Ceratotherium simum cottoni) that lived at San Diego Zoo, reduces the world population of this critically endangered subspecies to just five, all of which live in captivity and none of which are breeding. One more [...]

Australia is home to one of the exceptions, the white-throated snapping turtle (Elseya albagula), which can extract oxygen from water through its backside via a process called cloacal respiration. This unusual technique, shared by a handful of other turtle and fish species, gave the turtles an evolutionary advantage for millennia, [...]

    It’s a simple equation, really: If a species can’t reproduce, it will go extinct. A critically endangered species in Honduras faces that risk in a notable way. It turns out that the people who coexist with Valle de Aguán spiny-tailed iguanas (Ctenosaura melanosterna) not only like to eat the lizards they prefer the taste of [...]

    giraffes

    One of the world’s most iconic and beloved animals is quickly disappearing. Fifteen years ago about 140,000 giraffes (Giraffa camelopardalis) roamed the plains and forests of Africa.

    palila

    You have to hike a pretty long distance if you hope to see the critically endangered bird known as the palila (Loxioides bailleui), but if you’re lucky and work hard, you can walk their entire habitat in a single day. That’s because these beautiful yellow-headed birds live in just one place on Earth: the upper [...]

    Chimp in tree

    How’s this for irony?: A newly discovered plant named after the reserve in which it is supposedly found is endangered because the reserve isn’t actually located where people thought it was. According to the Wildlife Conservation Society (WCS), the new plant—Dorstenia luamensis, which was discovered in 2012 and described last month in the journal PhotoKeys—was [...]

    Amur tiger

    In 2001 a few tigers in Russia started to show signs of obvious distress. Endangered Amur (or Siberian) tigers (Panthera tigris altaica) were underweight, weak, disoriented and incapable of hunting as a result. At least four of the big cats had to be put down after they wandered into towns in search of food. One [...]
