Scientists Capture Video of Deepstaria, a Rarely Seen, Shapeshifting Jellyfish

Millions of years of evolution taking place beneath the sea's surface have produced some bizarre animals. Jellyfish are among the oldest—and strangest—of the bunch. Some have "transient" anuses that only form when necessary, and others can renew their life cycles indefinitely. Little is known about Deepstaria, a jellyfish recently spotted by the crew of the Nautilus research vessel in the central Pacific Ocean, but as the video below shows, it's no less unusual than other species of jellyfish.

As Live Science reports, scientists aboard the Nautilus were scanning the seafloor about halfway between the U.S. and Australia when they spotted a spooky-looking creature hovering in front of them. It soon became clear that cosplaying a ghost wasn't all it could do. The jelly unfurled its sheet-like bell to reveal a geometric mesh membrane used to distribute nutrients throughout its body—a telltale sign of Deepstaria. It spends the rest of the video putting on a show for its guests, transforming from something resembling a crumpled plastic bag to a billowing blanket shape.

Deepstaria enigmatica was discovered by the Jacques Cousteau-designed Deepstar 4000 submersible—the vessel the species is named after—in the 1960s. It's only been spotted about a dozen times in the years since, and many details of how it lives remain a mystery to researchers.

Deepstaria's most distinctive feature is its massive, flowing bell. It lacks the tentacles most jellyfish use to wrangle prey, and scientists suspect it instead uses its bell as a net when hunting. The specimen captured in this video appears to be harboring a stowaway: a bright-red, living isopod suspended inside the bell. It isn't clear if the creature hitched a ride on purpose to evade more ferocious predators, if it's some type of parasite, or if it's the jellyfish's lunch.

With so many undiscovered and understudied species living in the sea, the Nautilus research vessel is frequently stumbling upon extraordinary examples of ocean life. In 2016 alone, it recorded footage of a googly-eyed stubby squid and a mysterious purple orb.

The Reason Why a Puppy in North Carolina Was Born Bright Green

When a dog owner in Canton, North Carolina, first saw her new puppy, she knew exactly what to name him. Hulk the infant pup is much smaller than his namesake, but like the comic book character, he's green from head to toe.

As WLOS reports, Hulk was born with a coat of fur the color of avocado toast. He is one of eight puppies in a litter a white German Shepherd named Gypsy delivered the morning of January 10. Even though one came out lime-green, it was healthy, normal birth, according to Gypsy's owner Shana Stamey.

Hulk's unique coloration isn't a sign of any health issues. Meconium—or the matter in the intestines of a fetus—is mostly made of water, but it can also contain something called biliverdin. This chemical makes bile, and when it gets into the amniotic fluid of a birth sac, it can stain a puppy's fur green. This is especially noticeable when the newborn's fur is white, as in Hulk's case. You can see the rare phenomenon in the video below.

After a few weeks of baths and licks from mom, the meconium stains will eventually fade to reveal his natural white coat. But while he won't be green forever, Hulk gets to keep his colorful name for life.

Not-So-Fancy Feast: Your Cat Probably Would Eat Your Rotting Corpse

Cat enthusiasts often cite the warmth and companionship offered by their pet as reasons why they’re so enamored with them. Despite these and other positive attributes, cat lovers are often confronted with the spurious claim that, while their beloved furry pal might adore them when they’re alive, it won’t hesitate to devour their corpse if they should drop dead.

Though that’s often dismissed as negative cat propaganda spread by dog people, it turns out that it’s probably true. Fluffy might indeed feast on your flesh if you happened to expire.

A horrifying new case study published in the Journal of Forensic Sciences offers the fresh evidence. The paper, first reported by The Washington Post, documents how two cats reacted in the presence of a corpse at Colorado Mesa University’s Forensic Investigation Research Station, or body farm, where the deceased are used to further forensic science for criminal investigations.

The study’s authors did not orchestrate a meeting between cat and corpse. The finding happened by accident: Student and lead author Sara Garcia was scanning surveillance footage of the grounds when she noticed a pair of cats trespassing. The cats, she found, were interested in the flesh of two corpses; they gnawed on human tissue while it was still in the early stages of decomposition, stopping only when the bodies began leaching fluids.

The cats, which were putting away one corpse each, didn’t appear to have a taste for variety, as they both returned to the same corpse virtually every night. The two seemed to prefer the shoulder and arm over other body parts.

This visual evidence joins a litany of reports over the years from medical examiners, who have observed the damage left by both cats and dogs who were trapped in homes with deceased owners and proceeded to eat them. It’s believed pets do this when no other food source is available, though in some cases, eating their human has occurred even with a full food bowl. It’s something to consider the next time your cat gives you an affectionate lick on the arm. Maybe it loves you. Or maybe it has something else in mind.
