Watch a Cheetah Hunt Its Prey—From the Cheetah's Point of View

Even if you're a huge fan of wildlife documentaries, you've never seen a cheetah hunt quite like this. For PBS's latest Nature miniseries, Animals With Cameras, animal behaviorists strapped custom-made cameras on meerkats, seals, cheetahs, and more to capture never-before-seen footage.

"There's absolutely no way we could see this any other way," wildlife cameraman Gordon Buchanan says in the clip below, which follows a hunting cheetah as she and her siblings try to take down an eland, a type of antelope native to east and southern Africa.

The custom-made camera was strapped to the top of the cheetah's head, allowing it to record footage from the animal's point of view. The cameras were designed by Chris Watts of British Technical Films, a UK-based company that specializes in developing custom camera kits to capture wildlife and nature footage.

The cheetah-mounted cameras had to be extra-light, since the fast-moving predators were extremely sensitive to the device's weight. (As you, too, might be if you had a camera on your head while sprinting.) The straps that secured the camera had to allow enough airflow to keep the cat's head cool and be flexible enough that the animal could get the device off if it became too bothersome. And since running across the savannah at 70 mph can get a bit bumpy, the camera had to have stabilizing sensors to make the footage smooth, so it wouldn't make viewers queasy.

The result is a pretty spectacular scene following a cheetah from the moment it picks up the scent of its prey to the end of its hunt. Watch the full video below. We won't spoil how it ends.

The final episode of Animals With Cameras airs on February 14 at 8 p.m. Eastern Time.

How The Crown Saved the Corgis

Corgis may be both Queen Elizabeth II and the internet’s favorite dog breed, but their longtime association with the former has actually proven detrimental to their popularity in England. So much so that, in 2009, the stout little furballs were added to the UK Kennel Club’s list of native breeds that were “at risk of extinction.” Now, The Telegraph reports, their numbers are rising—thanks in part to the popularity of Netflix’s The Crown.

According to The Telegraph, the Queen’s love of the corgi is partly what caused its dip in popularity, as they “have long been regarded as a breed for the elderly and the genteel upper middle class.” But The Crown’s revisiting of the royal family in the early days of Elizabeth II’s reign (and the years leading up to it) have shown the Queen in a new, and much more stylish, light—and her beloved breed has reaped the rewards. In just the past two months, since The Crown’s second season dropped on Netflix in December, the Kennel Club has seen enough interest in the breed to take them off the endangered list entirely.

The Crown has certainly been important in the resurgence of the corgi breed,” Kennel Club public relations manager David Robson said. “It has increased interest in the breed. Following the transmission of the second series, searches for the breed puppies on our website went up by 22 percent.”

The dogs have proven to be a hit with viewers, as well as their costars. Claire Foy and Matt Smith, who portrayed Queen Elizabeth and Prince Philip in the show’s first two seasons, admitted that when they’re filming with the series' dogs, it’s the corgis who steal the show.

“When we’re with the corgis, then all the shots are about the corgis and you have to fit your acting around what the corgis are doing,” Foy explained in an interview with Off Set. “Which is absolutely … fine. And is the way it should be quite frankly.”

But even before Netflix unleashed its pricey royal drama on the world, the Queen’s dogs were finding their way back into the spotlight. In 2011, shortly after Prince William married Kate Middleton, BBC reported that the Cardigan Welsh corgi (a sort of cousin to the Pembroke Welsh corgi that the Queen prefers, though the Kennel Club lumps them into one category) saw a registration increase of 134 percent, which the group chalked up to the “royal wedding effect.”

Interest in the breed surged again in 2015, when the Queen—who has owned 30 of the dogs during her life, beginning with her childhood pooch Dookie—announced that she would no longer breed the pups, as she did not want to leave any young dogs behind in the event of her death. Adding to their pop culture cachet: During their first official interview after announcing their engagement, Prince Harry admitted that part of the reason he knew wife-to-be Meghan Markle was “the one” was because “the corgis took to [her] straight away.”

Drone Captures Massive Swarm of Jellyfish Off British Columbia That Weighs More Than 70 Tons

Drones have served science in myriad ways, from planting trees to vacuuming marine debris to predicting tornadoes. Now, a team of researchers has used one to measure the size of a massive bloom of jellyfish off the coast of British Columbia, Canada. And it's a monster: According to a new paper in the journal Marine Ecology Progress Series, the huge swarm weighed more than 70 tons.

That's at least 150,000 individual jellies.

"The size of the bloom surprised me. What was exciting was going from not being able to see the bloom easily, if at all, to instantly being able to find them from the air," says co-author Brian Hunt, the Hakai Professor in Oceanography at the University of British Columbia in Vancouver, B.C. "It is remarkable how tightly they group together."

The bloom is comprised of five species in the Aurelia genus, also known as moon jellies. They're found worldwide (and in aquarium exhibits), often gathering in quiet harbors and bays to feed on plankton, fish larvae, crustaceans, and mollusks.

Hunt and colleague Jessica Schaub conducted their survey in Pruth Bay, a peaceful waterway edged with dense forests, near Calvert Island on the province's central coast, roughly 375 miles north of Seattle. The Hakai Institute, a scientific research institution that supported the survey, faces the bay. The area is within the First Nations territories of the Heiltsuk and Wuikinuxv Nations.

This is the first time a drone has been used to locate and study jellyfish blooms, Hunt tells Mental Floss. Previously, scientists viewed the groups at water level, which provided a limited perspective on their true size and density. The aerial view can help researchers estimate the biomass of jellyfish more accurately and reveal aggregations' behavior, such as their movements in currents or tides.

The team deployed the drone from a research vessel positioned within the mass of invertebrates. While the drone captured aerial images, the researchers also sampled the waters with nets. Then, they compared the drone data and sampling, and estimated that the bloom could weigh anywhere from 70 to as much as 128 tons.

There isn't much long-term data about the blooms, Hunt says, but those living in the area are familiar with the jellies' appearances in the waterways. "I wouldn’t call these events common, but they are definitely consistent in their timing. We see this happening every four or so years, particularly the local fisherman who catch them as bycatch in their nets," William Housty, chair of the Heiltsuk Integrated Resource Management Department's board of directors, tells Mental Floss.

In the future, drones might help scientists interpret the blooms based on where, when, and how often they occur—as well as how they affect the surrounding ecosystem. Housty says these jellyfish may be following the pattern of warmer waters along the coast.

"We did notice higher numbers during the 2015 marine heatwave and the 2016 El Niño [also a warm event]," Hunt says. "It is possible that changes in the seasonal timing of the jellyfish life cycle might be as or more important than increasing numbers. For example, if jellyfish are more advanced in their life cycle in the spring, they might have a bigger predation impact on herring larvae."

Soon, thanks to aerial imagery, we might know more about the jellies' secret lives.
