Watch a Gulper Eel Inflate Like a Terrifying Balloon

Since launching in 2008, the Ocean Exploration Trust's Nautilus research vessel has live-streamed a purple orb, a transparent squid, and a stubby octopus from the bottom of the ocean. The latest bizarre example of marine life captured by the vessel is a rare gulper eel that acts like a cross between a python and a pufferfish.

As Thrillist reports, this footage was shot by a Nautilus rover roaming the Pacific Ocean's Papahanaumokuakea Marine National Monument 4700 feet below the surface. In it, a limbless, slithery, black creature that looks like it swallowed a beach ball can be seen hovering above the sea floor. After about a minute, the eel deflates its throat, swims around for a bit, and unhinges its jaw to reveal a gaping mouth.

The reaction of the scientists onboard the ship is just as entertaining as the show the animal puts on. At first they're not sure what they're looking at ("It looks like a Muppet," someone says), and after being blown away by its shape-shifting skills, they conclude that it's a gulper eel. Gulper eels are named for their impressive jaw span, which allows them to swallow prey much larger than themselves and puff up to intimidate predators. Because they like to lurk at least 1500 feet beneath the ocean's surface, they're rarely documented.

You can watch the inflated eel and hear the researchers' response to it in the video below.

Dream Job Alert: You Can Live and Work in Yellowstone National Park This Fall

Geysers. Charismatic wildlife. Camping. A supervolcano. Yellowstone National Park is home to so many things to see and do that you’d practically have to be embedded there to experience it all. Now, some will have a unique opportunity to live and work on the grounds this fall.

For the past year, the Helping Hands program at the park has recruited applicants to stay at one of the Yellowstone National Park lodges run by the Xanterra Travel Collection. The program offers part-time, short-term park jobs for people seeking to explore Yellowstone in greater depth. Workers spend about 20 hours a week working food service, housekeeping, and other duties and are able to stay in low-cost dorm-style accommodations. Meals are provided for a small biweekly fee. The rooms don’t have many amenities—there’s no television and Wi-Fi is slow—but you certainly won't be at a loss for things to do.

The five-week program begins for two groups on September 5 and 12 and lasts through October 15. In addition to lodging, workers also receive a $10.10 hourly wage. You can submit an application at the Yellowstone National Park Lodges website.

5 Terrifyingly Huge Spiders

This week, woman in Tasmania came upon a massive huntsman spider devouring a pygmy possum at a lodge in the island's Mount Field National Park. The alarmingly huge arachnid was at least the size of a grown man's hand, and it's not the only giant spider out there. The enormous spiders below can’t be dispatched by a shoe or a rolled-up newspaper. They're sure to give you nightmares—even if you're not an arachnophobe.

1. Poecilotheria rajaei

This species of tarantula, discovered in northern Sri Lanka in 2013, has a leg span of 8 inches. That's roughly the size of your face! It’s part of an arboreal group called tiger spiders, which are indigenous to India and Sri Lanka. A dead male specimen of P. rajaei—which is distinguished from other tiger spiders by the markings on its legs and abdomen—was first presented to scientists in October 2009 by a local villager; a survey of the area revealed enough females and juveniles that scientists are confident they've found a new species. “They are quite rare,” Ranil Nanayakkara, co-founder of Sri Lanka’s Biodiversity Education and Research, told WIRED. “They prefer well-established old trees, but due to deforestation the number have dwindled and due to lack of suitable habitat they enter old buildings.” P. rajaei was named after a police officer who helped scientists navigate the area where it was found.

2. Theraphosa blondi

Though Theraphosa blondi is called the Goliath bird-eating spider, it doesn’t actually eat birds. Reportedly, it got its name when an explorer saw it eating a hummingbird, but like other tarantulas, its diet consists mainly of insects, frogs, and rodents. But we’ll forgive you if you’re not comforted by that fact. After all, this spider can have a leg span nearly a foot across—the size of a dinner plate—and weigh up to 6 ounces, making it the largest spider in the world by mass. Its fangs, up to an inch long, can break human skin. (Though venomous, its poison won't bring down a human.) Native to South America, the spider makes noise by rubbing the bristles on its legs together; the sound can be heard up to 15 feet away.

3. Heteropoda maxima

Yet another reason to avoid dark caverns: Discovered in a cave in Laos in 2011, the giant huntsman spider has a leg span of 12 inches. It’s just one of over 1000 species of huntsman spider. These speedy arachnids can chase down their prey with ease and have legs that extend forward, like a crab’s.

4. Golden silk orb-weavers

These arachnids, of the genus Nephila, have a fearsome relative: the largest fossilized spider ever found is an ancestor. Females of this group of spiders, which are found around the world, can have leg spans up to 6 inches (the males are smaller). Though these orb-weavers typically eat large insects, in Australia, some of these spiders have been snapped eating snakes and birds that got caught in their strong, 5-foot-diameter webs.

5. Phoneutria nigriventer

Sure, Phoneutria nigriventer's nearly 6-inch leg span is scary—but there's something else about this spider that makes it even more terrifying: its venom, a neurotoxin that can be fatal to humans. In fact, along with P. fera, this spider is the most toxic on Earth (thankfully, a good antivenom exists). Native to Central and South America, P. nigriventer is also called the Brazilian wandering spider, for its tendency to roam the forest at night, and the banana spider, both because it hides in banana plants during the day and sometimes stows away in shipments of the fruit. When threatened, the spider lifts its front two pairs of legs and sways side to side, as you can see in the video above.
