The National Zoo Is Hoping to Spark a Love Connection Between Two Sloths

The Washington, D.C.-based National Zoo is playing matchmaker for a couple of two-toed sloths. As Smithsonian reports, the zoo acquired a female sloth in December 2019 with a plan to pair her with its longtime resident male. If successful, the new breeding program will mark the first time a sloth has been born at the zoo since 1984.

Athena, a 1.5-year-old sloth from the Ellen Trout Zoo in Lufkin, Texas, made her public debut at the National Zoo on December 22. She currently resides in the zoo's Small Mammal House with a pair of golden lion tamarins and a green aracari, a type of toucan.

The new arrival is what the zoo hopes will be one half of a breeding couple. The other half, a 34-year-old sloth named Vlad, has lived at the National Zoo for many years. The zoo had previously tried mating him with a female sloth named Ms. Chips, but they never appeared to hit it off—and if they did, the staff was unaware. Ms. Chips died two years ago without leaving any offspring.

Nurturing a relationship between two sloths is an appropriately slow process. Before they were officially introduced, Athena and Vlad became acquainted with each other's scents when the zoo staff swapped their blankets. The first time they met face to face was through a mesh barrier. If they express interest in spending more time together, the zoo will move them into the same exhibit.

Even if the animals do get along, they won't be welcoming a new baby any time soon. Female sloths don't reach sexual maturity until age 3, so it will be another year and a half before any serious breeding efforts can begin. According to the National Zoo, the sloth's conservation status in the wild is of "least concern." That means the future of the species doesn't hinge on Vlad and Athena's chemistry—but with decades having passed since a sloth was last born there, a newborn member of the species would be a welcome addition to the zoo.

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.

7 Animals That Appear to Fly (Besides Birds, Bats, and Insects)

The only animals that can truly fly are birds, insects, and bats. Other animals manage to travel through the air by gliding from great heights or leaping from the depths. Here are a few.

1. Devil Rays

The devil rays, in the genus Mobula, are related to manta rays. Their wingspan can grow up to 17 feet wide, making them the second-largest group of rays after the mantas. These muscular fish can leap several feet out of the water, but no one is quite sure why they do it.

2. Colugos

These tree-dwelling gliders are sometimes called flying lemurs, but they're neither true lemurs nor do they fly. These mammals in the genus Cynocephalus are native to Southeast Asia and are about the size of a house cat. Colugos can glide up to 200 feet between trees using their patagium, or flaps of skin between their front and hind legs that extend to their tail and neck (colugos are even webbed between their toes). In the air, they can soar gracefully through the forest, but on the ground, they look like an animated pancake.

3. Flying Fish

Flying fish

There are about 40 different species of flying fish in the family Exocoetidae, although they don't fly so much as they leap from the water with a push of their powerful pectoral fins. Most of the species live in tropical waters. Fish have been observed skipping over the waves for as long as 45 seconds and 650 feet. Scientists suspect that flying fish leap into the air to escape predators.

4. Paradise Tree Snake

The paradise tree snake (Chrysopelea paradisi) lives in the rain forests of Southeast Asia. It glides from the treetops by flattening its body out to maximize surface area, wiggling from side to side to go in the desired direction. Though the idea of a flying snake may be terrifying, C. paradisi is not harmful to humans.

5. Flying Geckos

Flying geckos, a group of gliding lizards in the genus Gekko, live in the wet forests of Southeast Asia. In addition to patagia that let them parachute from tree branches, the geckos have remarkably mutable skin that camouflages them against tree trunks extremely well.

6. Wallace's Flying Frog

Wallace's flying frog (Rhacophorus nigropalmatus) is found in Malaysia and Indonesia. This frog has long webbed toes and a skin flap between its limbs which allows it to parachute—float downward at a steep angle—from the treetops. Although Wallace's flying frogs prefer to live in the forest canopy, they must descend to ground level to mate and lay eggs.

7. Flying Squirrels

Flying squirrels in the subfamily Sciurinae include dozens of species. They are native to North America and Eurasia. When it leaps from a tall tree, a flying squirrel will spread its patagium until it resembles a kite or parachute. The squirrel can steer by moving its wrists and adjusting the tautness of its skin.
