The giant reptile was taken from Isabela Island in Ecuador's Galápagos archipelago as part of an early effort to sustain the species, which is native only to the remote Pacific island chain.
The popularity of antlers as rustic décor is threatening deer and elk in the Pacific Northwest. The animals can naturally shed antlers, but some people harass or kill animals to get at prized racks.
Tara body-slammed the neighbors' dog to save her then-4-year-old owner. When a Los Angeles shelter prepared to present its annual trophy, no dog's heroics could match the cat's.
To stop elephant slaughter in Africa, zoologist Sam Wasser spent years extracting DNA from elephant dung and tissue. Much of the world's poached ivory, he discovered, comes from just two hotspots.
Hormones from medical treatments wind up in wastewater, and that can be a problem. Some scientists think a version of a household chemical, hydrogen peroxide, could be part of the solution.
They didn't quite break the Internet, but the video of 700 goats on their way to a snack is definitely having a moment. We wanted to hear the story behind the herd.
Atlantic cod have become scarce along the coast, though catch limits have been reduced by 80 percent. Researchers are now tracking the sound of mating cod, hoping to help fishing boats avoid them.
If a starfish loses a limb, a new arm buds and grows in its place. But young moon jellies have a different strategy for self-repair: Existing limbs rearrange themselves to regain symmetry.
It's unknown what triggers an outbreak of Middle East respiratory syndrome. But scientists think the virus comes from camels. So until we stop it in animals, MERS will continue to cause trouble.
The rising waters wrecked the animals' enclosures, sending tigers, lions, bears, wolves and at least one hippo into the streets of the Georgian capital.
The Greek fisherman casting a net from his small wooden boat is a postcard image of the Mediterranean. But fish stocks are so low now that many fishermen say they can't make a living anymore.
That low price doesn't reflect the true state of Pacific bluefin: Scientists say it's in deep trouble. But fishermen who catch it say they're just trying to make a living — and obeying the law.
Migratory birds and humans have long relied on the odd creatures, and scientists now fear they're on the decline. This time each year, volunteers fan out along Mid-Atlantic coast to count the crabs.
Scientists have spotted chimpanzees routinely sipping palm wine from trees in Guinea. The study supports a theory that our common relatives evolved the ability to digest alcohol millions of years ago.
Years of drought have taken a toll on agriculture, particularly cattle ranching. Now instead of too little water, there's too much. But the rains may revive pastures and allow rebuilding of herds.
Last year, big fleets in the Bering Sea caught more halibut, by accident, than local fishermen caught on purpose. The big ships throw out that halibut; the local fishermen make their living from it.
The world has a lot of sad stories. But as a blog called Goats and Soda, we feel it is our duty to bring you a minute (and three seconds) of relief with the latest viral goat video.
That's what researchers found when they gave chimps a device that appeared to work like an oven. The findings add to the argument that our ancestors began cooking soon after learning to control fire.
The U.S. Department of Agriculture said it will allow pasteurized egg imports from the Netherlands to alleviate dwindling supplies and higher prices from the ongoing outbreak on U.S. poultry farms.
A new study sheds light on a longstanding ecological question: How do so many species like impalas and elephants co-exist when they're all feeding on the same limited foods?
Global sturgeon populations are collapsing — most notably in Russia, where caviar is known as black gold. That's fueling a market for illegal caviar and driving poachers to the Columbia River.
The largest outbreak of avian flu in U.S. history is ravaging poultry at farms in the Midwest. Sec. Tom Vilsack says there's no risk of transmission to humans, but egg prices may rise.
