As the new Planet Earth series has us remembering, nature is awe-inspiring, and unparalleled in its complexity, diversity, or cruelty. Observing the eternal arms race of species competing to claim a limited number of resources as it plays out through specialized biology over the course of millennia is humbling…

These are the famous Tsavo Man-Eaters. In 1898, they killed over 135 people, and stopped work on a railroad before they were finally shot. Like many male lions in the Tsavo region, they have no manes. A 10-year study shows us part of the reason why.

The sounds of fireworks and revelry echoed through the warm Oregon night as people throughout Portland celebrated Independence Day. It was July 4th, 1970. And among the crowds were three young men enjoying the triple pleasure of a holiday, a summer evening, and the vigor of youth.

Look, I don't want to promote fear of lions, which are amazing creatures. But they can open car doors, and that's just terrifying.

Last month we brought you footage of an African painted dog pack taking down a pregnant impala. Today, we bring you lions hunting a baby buffalo.

I always thought it was odd that lions were called the King of the Jungle when, in truth, they live on the savannah and in the bush. Still, they're definitely royalty among the African megafauna.

Lucien Beaumont, a guide at the Londolozi Game Reserve in South Africa, was observing a pride of lions on the move, when they surrounded something. "My imagination started to race, trying to figure out what they had found," he writes on his blog. He never imagined it would be a porcupine—or what would happen next.

There's a lion in the San Francisco Zoo that absolutely adores rhino dung: loves smelling it; loves rolling in it. A team of Stanford students found this out during a design-build course, and you know what they did? Those undergrads developed a custom three-pronged poop-chute for the lion lair.

Sometimes nature really is "red in tooth and claw," as Tennyson famously wrote. It's also red in horn, as this lioness found out recently.

Well, it looks like a hi and then it winds into a gentle smack. But still, the lion cub who stumbled upon this GoPro camera is just so adorable that I wouldn't mind getting pawed around by the little prince of the jungle.

We've always been speculating about battles between superheroes. We know the outcome of octopus versus shark. At last we have an expert speculating on lion versus tiger. Which one would win?

Nikon ambassador Chris McLennan and engineer Carl Hansen have created a small remote controlled four-wheel drive rover to roam the savanna and capture photos of curious lions, like the cute pride above. It's pretty neat. Watch it in action here.

Naturalists in Africa have long noted that some lions in Ethiopia look a bit different than regular lions, mostly on account of a dark mane that extends from the head, neck, and chest to the belly. They're also smaller and more compact. It wasn't known, however, if they represented a distinct species. But now, a…

Last week, we met a lion tamer who used his powers of persuasion to transform his cats into a stately throne. Today, we will examine the defunct practice of corralling large, semi-unpredictable cats into motordromes, training them to sit in sidecars, and tearing ass up perilous inclines with these apex predators in…
