Sharks are pretty eclectic eaters. They’ll go for prey ranging from fish and invertebrates to sea mammals and turtles. A shark may even have a chomp on the odd surfer. If they can catch it, or scavenge it, and it’s made of meat, sharks will generally eat it. A new study identifying the contents of

If you pictured a fight between a snake and a squirrel, you probably wouldn’t bet on the squirrel coming out on top. But that’s exactly what happened in a particularly gruesome case in 2009, caught on camera by William Leggett, who was a ranger at West Texas’ Guadalupe Mountains National Park. The photo below shows

If you think your mom is laying it on thick about producing grandchildren, take heart: At least you’re not a male bonobo. Bonobo mothers have been seen performing a variety of behaviors that seem to lend their sons an advantage when it comes to fathering babies, according to a study published Monday in Current Biology

It’s long been known that cannabis plants are indigenous to Central Asia, but a new study provides a fresh focus on where exactly this genus may have first evolved millions of years ago. Documents dating back to the middle ages show humans have been hypothesising about the geographical origins of cannabis for over a thousand

Peacock spiders are so adorable, they stand a chance to sway the feelings of the most seasoned spider hater. These creatures are tiny –  a mere 5 millimetres (0.2 inches). They’re also fluffy, the males have incredibly colourful butts, and they love to dance. Now we’ve discovered these spiders also have an interesting superpower – the

Researchers have pinpointed a previously unknown source of volcanoes in the extreme depths of Earth – in the transition zone between the upper and lower mantle. Until now, we thought we had a handle on the ways in which volcanoes form, welling up from the molten regions in the upper mantle beneath our planet’s crust,

Unlike human history, when nature repeats itself, there’s usually a good reason. For the white-throated rail (Dryolimnas cuvieri), all it took was a peaceful reef Eden, free from predators and competition. On the remote Aldabra atoll in the Indian Ocean, scientists have discovered that the same species of bird has lost its ability to fly

Scientists have found a bunch of microscopic creatures that could be totally new to science – but it’s an exceptional challenge to determine who is who when the tiny things you’ve discovered are actually the larva of animals that look completely different in their adult stage. The little-known animals in question are called phoronids, or

Amber from Myanmar in Southeast Asia is turning out to be an incredibly rich resource for examining the natural world of 100 million years ago. In the last year, it’s turned up frogs, snails, a snake, weird feathers, and some pretty wacky bugs. What do all of those have in common? They’re land-dwellers. But now

There’s no denying that keeping livestock has deeply benefited humanity over the millennia. But, while sheep and cows may have adapted well to farm life, there’s one animal humans like to eat that would fare poorly in farms. Octopuses, scientists have argued in a new essay, should never be farmed – not just because of

Today the Australian Koala Foundation announced they believe “there are no more than 80,000 koalas in Australia”, making the species “functionally extinct”. While this number is dramatically lower than the most recent academic estimates, there’s no doubt koala numbers in many places are in steep decline. It’s hard to say exactly how many koalas are

When you’ve been surviving in all sorts of environments for billions of years, you pick up a few tricks for harvesting light as efficiently as possible – and now long-living, light-emitting microalgae could be about to help us develop the next generation of solar panels. These fluorescent algae are able to capture up to 95%

In recent years, it’s emerged that some dinosaurs – considered scaly and reptilian for many years – were actually wearing feathers. But a newly discovered species of scansoriopterygid dinosaur sports a different style. This tiny creature had bat-like wings: leathery, not feathery. It’s called Ambopteryx longibrachium, and it was just 33 centimetres (13 inches) long.

Along the Black River in North Carolina, bald cypress trees have been quietly growing for millennia. Quite literally so: Scientists recently found trees over 2,000 years old – including one that is at least 2,624 years old. That makes it the fifth-oldest known non-clonal tree in the world. (Utah’s Pando, an ancient quaking aspen forest,

Here’s a question for you. If A is greater than B, and B is greater than C, then is A greater than C? It’s a simple puzzle, something children can solve. In fact, even animals have demonstrated the form of reasoning – called transitive inference – that we use to answer this kind of problem.

For most of us, the jump from meat-eater to vegetarian is a big one. For the giant panda, the switch was all too easy. Despite a long family history of meat-heavy meals, this large bear now feeds almost exclusively on tough bamboo – a change its ancestors made more than 2 million years ago. For

In the mountainous cloud forests of Borneo, nothing goes to waste, and that includes waste itself. Here, the largest carnivorous plant on Earth has evolved to become a sort of customised outhouse for local tree shrews (Tupaia montana). With a toilet seat perfectly contoured to the mammal’s backside, this huge, jug-shaped pitcher plant (Nepenthes rajah)

Two tiny tyrannosaurid skeletons have just filled in the fossil record, elucidating the humble origins of the Cretaceous’ mightiest predator, Tyrannosaurus rex. Dating back to around 92 million years ago, the two tyrannosaurs hail from the Zuni Basin in New Mexico. They stood just 1 metre (3 feet) tall and have been named Suskityrannus hazelae.

Amongst the huge variety of life on Earth, there are some mighty resilient microorganisms out there. Now, scientists have tracked down an ocean microbe that survives by breathing arsenic – the chemical element we humans regard as a notorious poison. The researchers think this is an ancient survival strategy used in the distant past when oxygen

An alleged Russian spy whale is refusing to leave a Norwegian port city, in what appears to be a high-profile defection after a week of global attention on the unnamed beluga. Norwegian Directorate of Fisheries official Jorgen Ree Wiig told The Washington Post that the beluga “was the first thing I saw outside of the

During the last Ice Age, more than 10,000 years ago, the bridge between North and South America was guarded by a daunting array of beasts, including a wolf-like carnivore and the largest bear ever to roam the Earth. An ancient graveyard, buried at the bottom of an underwater cave in Mexico, has turned up not

You can find snakes in Australia pretty much anywhere. At the beach. On your car. But this three-eyed slitherer discovered in the Northern Territory is obviously all kinds of special. Found by rangers near a small town called Humpty Doo just outside of Darwin, the three-eyed carpet python looks to be sporting three fully functioning

Life isn’t easy at the bottom of Challenger Deep – at nearly 11,000 metres (36,000 feet) the deepest point of the oceans – and scientists just shed some light on how tiny creatures are able to survive at these phenomenal depths. It turns out that the Hirondellea gigas amphipods (small crustaceans) manufacture themselves tiny suits

Breaking news: Yeti are real, and they’re on the move – at least according to the Indian army, which said Monday that its mountaineering expedition team stumbled upon a set of “mysterious footprints” in Nepal this month. No, we are not confirming that this elusive snowman actually exists. But while the prints might be a

For the northernmost herbivores on Earth, foraging for food has never been easy. Bound to the icy tundras of an Arctic archipelago, the wild Svalbard reindeers of Norway (Rangifer tarandus platyrhynchus) are accustomed to sparse vegetation. But what they are dealing with now is far beyond that. With global warming causing more rain and less snow,

Scientists have discovered a new species of crab that swam the seas 95 million years ago — and behold, it could be the next Pixar character. The small, pocket-size crab, named Callichimaera perplexa, was different than its modern cousins. This crab sported a tiny lobster-esque shell, with legs flattened like oars, and huge Pound Puppies-style

Deep in the Brazilian Atlantic Forest live tiny frogs that are bright orange, toxic, and glow ultraviolet, thanks to revelations from new research. It’s the first known case of an amphibian showing “exceptional” fluorescence right through their skin. “The origin of the fluorescence lies in the dermal bone of the head and back, visible through

Given the fervour with which naturalists scoured Southeast Asia in the 19th century looking for new bird species, you’d think the region would be tapped out. But nature can still find ways to sneak up on us: Two previously undescribed species have only just been discovered in Indonesia. They both belong to the genus Zosterops,

Apes . . . well, ape. Two gorillas at Virunga National Park in Congo have taken the Internet by storm by posing – on two feet – in a photograph with park rangers. The rangers posted a selfie on Facebook late last week showing two orphaned female gorillas, Ndakazi and Ndeze, standing tall beside them in the Senkwekwe Center

California is notorious for its earthquakes, but a stunning new discovery reveals for the first time just how much we’ve underestimated its omnipresent earth-shaking potential. By the time you just about finish reading this story, in fact, Southern California will probably have experienced another quake – based off a new, unprecedented deep dive into 10

Slime mould might easily be one of the strangest life forms on our planet. They are neither plants, animals, nor fungi, but various species of complex, single-celled amoebas of the protist kingdom. Sometimes they form colonies able to grow, move, and even exhibit a strange kind of intelligence. Even without a nervous system, they are

Have you ever seen a giant red jellyfish light up the night sky for a split second? If you have, you’re not imagining things. You’ve just witnessed a lightning-like electrical discharge high in the atmosphere known as a sprite. Paul Smith captured the elusive phenomenon Wednesday night as storms raged over northwest Oklahoma and the

In the Hollywood blockbuster The Core, the planet’s core suddenly stops rotating, causing Earth’s magnetic field to collapse. Then bursts of deadly microwaves cook the Colosseum and melt the Golden Gate Bridge. While “nearly everything in the movie is wrong,” according to Justin Revenaugh, a seismologist from the University of Minnesota, it is true that

So you’ve discovered an unusual winged insect preserved in amber, and it happens to have a superb set of mouth parts dangling from its head.  You could name it after a president’s body part, maybe. If not David Attenborough. Again. Or just do what one researcher did with a specimen that doesn’t seem to fit

A beautiful spring morning at the Topeka Zoo in Kansas turned tragic Saturday when a male Sumatran tiger attacked a keeper, inflicting wounds that sent her to a hospital. Although keepers are never supposed to be in the same space as the tigers, they found themselves together in the outdoor habitat that morning for reasons

Butterflies are like the Bear Grylls of the Amazon rainforest. Faced with a nutrient-poor environment, these beautiful creatures will drink just about anything to survive. That goes for muddy river banks, sweaty clothing, puddles of urine, and of course, the ‘tears’ of turtles. It’s hard to believe until you see it with your own eyes.

There’s something about the meandering streak of lightning that implies random chaos. Yet bolts from the blue not only hit the same places with regularity, but successive discharges often reuse the exact same channel. It’s never been entirely clear how the path laid down by one bolt sticks around for repeat performances, but new research

Just when you think orcas couldn’t possible be any more awesome, they get even better. New evidence shows these whales are really good at scaring off the most feared beast in the sea. Yep. Orcas have toppled the great white shark off their ‘apex predator’ throne. A team of marine scientists has found that great

Proof that families come in all shapes, sizes and species, three eagles – two dads and a mom – are raising three, fluffy-feathered eaglets in a nest near the Mississippi River this spring. According to the Stewards of the Upper Mississippi River Refuge, all three birds, Valor I, Valor II (dads) and Starr (mom), “take

A Florida man was killed on Friday by what ornithologists say is the “world’s most dangerous bird“. It was a cassowary – an enormous, flightless bird around which even experienced zookeepers take precautions. He raised the animal on his farm, along with other exotic birds, authorities said. Police identified the man as 75-year-old Marvin Hajos.

Over the years, researchers have learned a lot about dinosaur anatomy, but there’s one feature that keeps eluding us.  Of all the dinosaur tracks discovered, only a rare few, far less than one percent, show any traces of skin. It’s a serious blindspot, especially when the patterns that this organ makes are like fingerprints, showing

In the sandy seabeds of temperate climates, a curious flatworm thrives. It’s called Paracatenula, and it has neither mouth, butt, nor gut. These shortcomings don’t slow the worm down, though – a symbiotic relationship with bacteria that live inside it keeps it alive. It works so well, in fact, they’ve been doing it for over

We’ve still got so much of the undersea world to explore, not least the Mariana Trench – the deepest natural trench in the ocean – which goes down 10,994 metres (36,070 feet) in places. Now another fantastic find from this subaqueous abyss has just been revealed. The most comprehensive microbial analysis of the trench to

Although the image above might make you think it’s had an Instagram filter added, what you’re looking at is pollen – lots and lots of pollen. The images were taken by photographer Jeremy Gilchrist on Monday in Durham, North Carolina and honestly, if you’re feeling a little sneezy just looking at it, you’re not alone.

Sixty-five million years ago, planet Earth was pummelled by a wave of extinction that left few marine organisms alive. Now scientists are trying to coax what’s left out of the abyss and into the limelight, baiting some ancient creatures with a rare delicacy of the past. A gross, yet fascinating new video shows a troop

Archaeologists just pried another secret of our past from the clutches of the earth, welcoming a new human species to our growing family tree. This discovery began with an ancient foot, or what was left of one. A foot bone, called the third metatarsal, was found in the Callao Cave on the Philippine island of

For 430 million years, nestled in some rocks in England, Cthulhu waited, dreaming. Now it’s finally seen the light of day, and it’s honestly a lot smaller than we were expecting. This fossilised Cthulhu is related to sea cucumbers, and dates back to the Silurian period, when the first bony fish appeared. Its three-centimetre (1.1

It wasn’t ash that killed the victims of volcano Vesuvius in Pompeii and Herculaneum in 79 CE. It wasn’t lava. It was something called pyroclastic flows – extremely hot clouds of volcanic gas and debris that can move at insane speeds. Pyroclastic flow speeds are so intense, they seem to defy the laws of physics,
