Wolverines have a reputation as voracious, flesh-ripping hellions, but their tamer predilection for raising their young in deep, snowy dens might prove more dangerous to the species.
Coyotes are colonizing many of America’s biggest cities, challenging our notions of where wildlife belongs.
Another example of awesome nature in action: these South American insects walk around with "explosive backpacks" capable of creating toxic blue goo to take out opponents -- and themselves.
Few humans would be jealous of the naked mole rat’s fleshy, squishy appearance, but many might envy the animal’s imperviousness to aging.

Floridians are accustomed to sharing their lawns and golf courses with unruly alligators. Now the more bashful American crocodile is jostling for space and attention.
The scalloped hammerhead has a doppelganger. So what was once a single threatened species is now two -- and both are worse off than we thought.
A hearty slow-growing seagrass that blankets the floor of the Mediterranean was able to withstand the last ice age. But can it survive climate change?
Human waste is running offshore in the Caribbean and infecting elkhorn coral -- critical habitat for other sea creatures -- with one bad bug.
Too many brothers mean big trouble for female marmots. They don’t tease her or pull hair, but they could ruin her future family life.

They’re ugly. They ooze slime. Their digestive systems are partially on the outside. They creep along the seafloor and eat sunken whale corpses. And hagfish could represent the transitional form to vertebrate species like our own.
As honeybees continue to desert their hives and die in large numbers, new research suggests that the insects may respond to stress in ways that seem an awful lot like humans do.
This conveniently transparent flatworm species engages in some particularly kinky reproductive practices (by human standards, at least).
