Predator

The Tyrannosaurus rex (T. rex) is known for its bone-crushing bite, gigantic size, and famously small forelimbs. But why these large, carnivorous theropod dinosaurs evolved tiny arms has long been debated.

Bus-sized cephalopods reminiscent of the legendary kraken may have sat at the top of the food chain, using their smarts to hunt down prey in the oceans of the Late Cretaceous.

There are more than 800 species of carnivorous plants, and despite their diverse designs, the one thing they have in common is that they are built to trap and kill all prey. Or so we've believed – until scientists discovered how this meat-eater works.

Sometimes, the most important paleontological discoveries may come from the most disgusting materials. A fossilized vomit sample dating back nearly 300 million years revealed how an ancient mammal gorged on all manner of prey.

Step aside, Van Gogh. New research shows that several orb-weaving species create giant web-mounted “doppelgängers” convincing enough to confuse potential predators. It’s a clever form of deception that nudges the line between instinct and ingenuity.

For the first time ever, a unique cooperative hunting arrangement between dolphins and orcas has been documented. Researchers believe killer whales find salmon by tailing dolphins, who in turn benefit from bite-sized fish pieces.

In the world of flying, stinging insects, Asian giant hornets reign supreme, reaching impressive sizes and wielding mighty venom-filled lances. Now, researchers have found an unlikely hero that can vanquish these buzzing badasses: the humble frog.

Humpback whales may look like gentle giants, but each year they undertake nature's most extreme crash diet, shedding 36% of their mass in less than two months. New insights into their epic annual swim has identified just how huge their fat loss is.

Unless you're a nut, cute little squirrels pose little threat – but they could have a surprising murderous streak. After watching squirrels in California for 12 years, scientists have seen them actively hunt and kill small rodents this past summer.

Some species have an incredible knack for hacking others to get what they want. Scientists have now discovered a fascinating new example – some spiders have been seen manipulating fireflies’ flashes to attract more bugs to their webs.

Mowing might seem like a pretty sensible way to keep weeds at bay. But in the case of the silverleaf nightshade, the activity puts the plant into survival mode causing it to fight back with some pretty powerful defense mechanisms, says a new study.

It almost sounds like a fairytale: a tiny ant dramatically impacting a giant lion. But thanks to a study that reveals just how interconnected all life forms really are, researchers have just figured out that it happened on the savannas of Africa.
