10 Curious Facts About the Platypus

The platypus is arguably one of the most distinct animals on the planet. Here are a few things you might not have known about this quirky creature.

1. THEY DON'T HAVE A STOMACH.

Platypuses (platypodes and platypi are technically also correct, but much rarer in use) aren't the only animals to forgo an acid-producing part of the gut; spiny echidnas, and nearly a quarter of living fishes all have a gullet that connects directly to their intestines.

2. THEIR BILL GIVES THEM A "SIXTH SENSE."

A platypus’s bill is comprised of thousands of cells that give it a sort of sixth sense, allowing them to detect the electric fields generated by all living things. It’s so sensitive that the platypus can hunt with its eyes, ears, and nose all closed, relying entirely on the bill’s electrolocation.

3. THEY USED TO BE GIANT.

The ancient versions of a lot of modern animals, including penguins, were oversized monsters compared to the animals we know today. And platypuses are no different. In 2013, the discovery of a single tooth helped researchers identify a prehistoric platypus that was more than three feet long—double the size of the modern animal.

4. MONOTREME MEANS "SINGLE HOLE" IN GREEK.

Platypuses are one of only five species of extant monotremes—just them and four species of echidna—which split from the rest of the mammals 166 million years ago. These egg-laying mammals get their name from the hole that serves as both an anus and a urino-genital opening. In 2008, scientists deciphered the entire DNA of the duck-billed platypus and determined that, in accordance with the animal’s somewhat bizarre appearance, the platypus shared genes with reptiles, birds, and mammals.

5. THEY NURSE WITHOUT NIPPLES.

Although platypuses are born out of leathery eggs, the babies nurse from their mother. Female platypuses, however, don’t have nipples. Instead, their milk is released out of mammary gland ducts on their abdomen. The babies drink it up by sucking it out the folds of their mother's skin, or her fur.

6. THE MALES HAVE VENOMOUS SPURS.

Platypuses are one of just a few venomous mammals, which is one of their more reptilian characteristics. But unlike snakes, a platypus’s venom isn’t in his teeth. Instead, males have a hollow spur on each hind leg from which venom is dispensed—but only sometimes. Although the spur itself is always there, the venom gland to which it is connected is seasonally-activated and only produces venom during mating season, indicating that its use is for fending off competing males.

7. THEY HAVE RETRACTABLE WEBBING.

Although they can only stay submerged in water for a few minutes—they are mammals, after all—platypuses are much better suited to scooting around in water than they are on land. Much like an otter, they prune their thick coat to add air bubbles that act as insulation in the cool rivers where they hunt. Out on land, the platypus's short limbs mean it has to exert 30 percent more energy than a similarly sized land-based mammal just to move around . All that said, they do have one particular adaptation to ease their terrestrial travel: The webbing between their front claws—a boon when paddling through streams—retracts when the platypus ambles up the riverbank to expose sharp claws.

8. SCIENTISTS THOUGHT THE FIRST KNOWN PLATYPUS WAS A HOAX.

When the first platypus specimen was sent back to England from Australia in the late 18th century, the scientists who examined it thought that someone was playing a trick on them. "It naturally excites the idea of some deceptive preparation by artificial means," zoologist George Shaw wrote in the first scientific description of the platypus, published in 1799. That said, one of the most remarkable and weird aspects of the platypus—its ability to lay eggs—wasn’t discovered for another 100 years.

9. THEY USE GRAVEL AS MAKESHIFT TEETH.

Platypuses don’t have teeth inside their bill, which makes it difficult to chew some of their favorite foods—but they have worked out a pretty ingenious solution. Along with worms, insects, shellfish, and whatever else these bottom-feeders scoop up to make a meal out of, the platypus also picks up gravel from the riverbed. The platypus packs the whole lot into pouches in his cheek to carry it up to the surface where he munches away, using the bits of gravel as makeshift teeth to break up some of the tougher food.

10. THEY USE THEIR TAILS FOR ALL SORTS OF THINGS.

Unlike beavers, which have very visually similar tails, platypuses don't use their tails to slap the water in warning, or even to move them through the water. Most of the time, the primary function of the platypus's tail is just to store up to nearly half of the animal's body fat in case of a food shortage. A female platypus also uses her tail to hold incubating eggs against her warm body.

Massive Swarms of Migrating Dragonflies Are So Large They’re Popping Up on Weather Radar

What do Virginia, Pennsylvania, Indiana, and Ohio all have in common? Epic swarms of dragonflies, among other things.

WSLS-TV reports that this week, weather radar registered what might first appear to be late summer rain showers. Instead, the green blotches turned out to be swarms of dragonflies—possibly green darners, a type of dragonfly that migrates south during the fall.

Norman Johnson, a professor of entomology at The Ohio State University, told CNN that although these swarms happen occasionally, they’re definitely not a regular occurrence. He thinks the dragonflies, which usually prefer to travel alone, may form packs based on certain weather conditions. If that sounds vague, it’s because it is: Johnson said that entomologists haven’t worked out all the details when it comes to dragonfly migration. They do know that the airborne insects cover an average of eight miles per day, while some overachievers can fly as far as 86.

Based on the radar footage shared by the National Weather Service’s Cleveland Office, the dragonfly clouds seem almost menacing. But, while swarms of any insect species aren’t exactly delightful, these creatures are both harmless and surprisingly beautiful, at least up close. Anna Barnett, a resident of Jeromesville, Ohio, even told CNN that witnessing the natural phenomenon was “amazing!”

Amazing as it may be to see, it’s hard to hear news about unpredictable animal behavior without wondering if it’s related in some way to Earth’s rising temperatures. After all, climate change has already affected wasps in Alabama, polar bears in Russia, and no doubt countless other animal species around the world.

6 Fall Festivals Around the World That Celebrate Animals

Where would humans be without animals? Chickens and cows give us eggs and milk, providing nourishment (and also cake). Horses, donkeys, and water buffalo are as hardworking as any person, and thanks to our pets, we always have a source of love and entertainment to come home to. It's time we celebrate animals more often, and to get you started, here are six fall festivals around the world that do just that.

1. Kukur Tihar

A big part of Tihar, a five-day Hindu festival held in late autumn in Nepal, is giving thanks to other species. Crows, believed to be the messengers of death, are worshipped on the first day. Cows are worshipped on the third, and often oxen on the fourth. The second day, though, is all about man's best friend. Dogs are described favorably in Hindu religious texts, and it’s believed that they can warn people of impending danger and even death. In a ceremony called Kukur Tihar, people place flower garlands around the necks of both pet dogs and stray dogs to show their respect. A red dot (tika) is placed on their foreheads in an act of worship, and naturally, the dogs are spoiled with lots and lots of treats.

2. Transhumance Festival

In Spanish, this festival in Madrid is called Fiesta de la Trashumancia. The word transhumance refers to the act of moving herds of livestock to different grazing grounds depending on the season. In practice, it's quite the spectacle. Thousands of sheep have been led through the streets of Madrid each autumn since the festival was formally established in 1994. Men and women in traditional garb lead the way, singing and dancing along the parade route in celebration of centuries-old shepherding traditions.

3. Monkey Buffet Festival

Visitors to Thailand’s temples are advised not to feed the monkeys (they can get awfully handsy), but the locals of Lopburi make an exception on the last Sunday of November. On this day, towers of fruit and banquet tables containing several tons of food and even cans of Coca-Cola are set up in the ruins of a 13th-century temple. Once a sheet is removed to unveil the spread, it doesn’t take long for Lopburi’s thousands of macaques to arrive. Thailand's reverence for monkeys dates back some 2000 years to legends surrounding the monkey king Hanuman and his heroic feats. Nowadays, the creatures are considered a sign of good luck in the country.

4. Woolly Worm Festival

The woolly worm is to Banner Elk, North Carolina, what the groundhog is to Punxsutawney, Pennsylvania. According to local folklore, the color of this fuzzy caterpillar can be analyzed in autumn to predict how severe the forthcoming winter will be. The 13 segments on its body are thought to correspond to the 13 weeks of winter—more black means colder weather and snow, while more brown means the weather will be fair. To make this prognostication process more official, the Woolly Worm Festival was established on the third weekend of October in 1978. This year, it will be held October 20-21. A worm race is the main event, and the caterpillar that climbs the fastest up three feet of string gets the honor of helping to predict the winter (plus a $1000 cash prize for the worm’s coach). “Patsy Climb” and “Dale Wormhardt” were a couple of past competitors.

5. Pushkar Camel Fair

The Indian state of Rajasthan is a vibrant place. It’s home to the Pink City, Blue City, and Yellow City, and it also hosts a colorful cultural event each November called the Pushkar Camel Fair. Celebrated on a full moon day of the Hindu lunar calendar, it’s one of the largest fairs of its kind in the world. The annual gathering is a chance for traders to show off their camels and livestock, while also celebrating local culture and traditions. Both the people and camels sport brilliant attire, participate in a variety of competitions, and dance to lively music. (Yes, there’s video evidence of a dancing camel, but the word dance is used loosely.)

6. Birds of Chile Festival

Held each fall in Viña del Mar along Chile's Pacific coast, the Festival de Aves de Chile celebrates the beauty and diversity of the country's birds. Festival-goers have the chance to see Chile’s national bird—the wide-winged Andean condor, which happens to be one of the largest flying birds in the world—as well as other feathered friends in their natural environment. A series of excursions and talks featuring bird experts are organized each year.
