Herbivores—animals too weak to even kill and eat another, weaker animal—may be in for an “enormous” die-off soon. I suppose this is our fault, also?

A new study published Thursday in the journal Science has found that, if climate change continues apace, one in six species on the planet could face extinction.

One quarter of the world's shark and ray species are in danger of going extinct in the next two decades. Mega congrats to humans for helping to defeat these killers!

A species of frog named after Charles Darwin didn't fare so well in the evolutionary sense — scientists believe that the frogs — discovered by Darwin himself in 1834 — have all died off.

Moose are dying off across North America—and no one knows why.

Scientists in Australia are hopeful that they can bring back a strange species of frog that went extinct a quarter century ago. The Southern gastric brooding frogs, amphibians native to Queensland in eastern Australia, were best known for its strange parental habits (the mother would swallow the eggs after they hatched and regurgitate the completely developed offspring).

This is why we can't have nice things anymore. Do you see that majestic beast? Well that's as close as you'll ever get to seeing a Javan rhino because now they're extinct (in Vietnam).

Sad news out of the Galapagos Islands: Lonesome George, believed to be the last remaining member of the Pinta Island giant tortoise subspecies, was found dead in his corral yesterday morning by his caretaker, Fausto Llerena.

We all gasped in amazement at photos of a black rhinoceros being airlifted upside down to an area of South Africa where it stood a better chance at reproducing. Inconceivably, a new report suggests there's no other rhinos for it to reproduce with.

According to a new conservation study, one-fifth of all plant and animal species qualify for the Red List of Threatened Species, meaning they are "facing wipeout." So, basically, if we work hard, we can probably finish them off by 2100.

Less than 1 percent of oil-soaked birds survive. Now that the gulf is awash in oil, what do we do with this epidemic of slowly suffering wildlife? We've reached the point that mass euthanasia may be the kindest option.

Snakes! Nobody likes them. Especially Salma Hayek. The actress was recently doing an interview when something large slithered onto the scene and sent her shrieking. She may not shriek for long, though. All the snakes are dying, science fears.
