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.

This Wall Chart Shows Almost 130 Species of Shark—All Drawn to Scale

Shark Week may be over, but who says you can’t celebrate sharp-toothed predators year-round? Pop Chart Lab has released a new wall print featuring nearly 130 species of selachimorpha, a taxonomic superorder of fish that includes all sharks.

Called “The Spectacular Survey of Sharks,” the chart lists each shark by its family classification, order, and superorder. An evolutionary timeline is also included in the top corner to provide some context for how many millions of years old some of these creatures are. The sharks are drawn to scale, from the large but friendly whale shark down to the little ninja lanternsharka species that lives in the deep ocean, glows in the dark, and wasn’t discovered until 2015.

You’ll find the popular great white, of course, as well as rare and elusive species like the megamouth, which has been spotted fewer than 100 times. This is just a sampling, though. According to World Atlas, there are more than 440 known species of shark—plus some that probably haven't been discovered yet.

The wall chart, priced at $29 for an 18” x 24” print, can be pre-ordered on Pop Chart Lab’s website. Shipping begins on August 27.

Can You Really Suck the Poison Out of a Snakebite?

Should you find yourself in a snake-infested area and unlucky enough to get bitten, what’s the best course of action? You might have been taught the old cowboy trick of applying a tourniquet and using a blade to cut the bite wound in order to suck out the poison. It certainly looks dramatic, but does it really work? According to the World Health Organization, approximately 5.4 million people are bitten by snakes each year worldwide, about 81,000 to 138,000 of which are fatal. That’s a lot of deaths that could have been prevented if the remedy were really that simple.

Unfortunately the "cut and suck" method was discredited a few decades ago, when research proved it to be counterproductive. Venom spreads through the victim’s system so quickly, there’s no hope of sucking out a sufficient volume to make any difference. Cutting and sucking the wound only serves to increase the risk of infection and can cause further tissue damage. A tourniquet is also dangerous, as it cuts off the blood flow and leaves the venom concentrated in one area of the body. In worst-case scenarios, it could cost someone a limb.

Nowadays, it's recommended not to touch the wound and seek immediate medical assistance, while trying to remain calm (easier said than done). The Mayo Clinic suggests that the victim remove any tight clothing in the event they start to swell, and to avoid any caffeine or alcohol, which can increase your heart rate, and don't take any drugs or pain relievers. It's also smart to remember what the snake looks like so you can describe it once you receive the proper medical attention.

Venomous species tend to have cat-like elliptical pupils, while non-venomous snakes have round pupils. Another clue is the shape of the bite wound. Venomous snakes generally leave two deep puncture wounds, whereas non-venomous varieties tend to leave a horseshoe-shaped ring of shallow puncture marks. To be on the safe side, do a little research before you go out into the wilderness to see if there are any snake species you should be particularly cautious of in the area.

It’s also worth noting that up to 25 percent of bites from venomous snakes are actually "dry" bites, meaning they contain no venom at all. This is because snakes can control how much venom they release with each bite, so if you look too big to eat, they may well decide not to waste their precious load on you and save it for their next meal instead.
