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.

A Nubian Goat Named Lincoln Was Just Sworn in as the Mayor of Fair Haven, Vermont

Lincoln the goat may not be housebroken, but she had no problem winning the race for mayor of Fair Haven, Vermont. The new mayor was officially sworn in on Tuesday, March 12, and before signing the oath of office with her hoof print, she marked the occasion by defecating on the town hall floor, the Boston Globe reports.

Prior to getting into politics, Lincoln the droopy-eared Nubian goat lived a simple life. A local family looking for a way to maintain the unruly vegetation on their property had purchased her two years ago when she was 1 year old. At age 3, Lincoln transitioned from munching grass full-time to running for public office.

Though Lincoln's win is impressive, her election didn't involve beating any human candidates. Town Manager Joseph Gunter came up with the idea to hold an election for honorary pet mayor of Fair Haven as way to raise money for a new playground. For a $5 fee, local kids were allowed to nominate the pet of their choice to be town mayor. Lincoln bested more than a dozen candidates, including a gerbil named Crystal and a pacifier-sucking dog named Stella, for the position.

The stunt didn't raise much money—the town came away with just $100 for the playground—but it did earn Fair Haven international attention. In order to go down in history as world's longest-serving animal mayor, Lincoln has to stick around for a while; Stubbs the cat was mayor of Talkeetna, Alaska for 20 years.

The 10 Most Popular Puppy Names of 2019

If you brought home a new dog or puppy recently and named it Luna, you’re far from the only one. The name, which means moon in Latin, is the most popular puppy name for 2019.

This analysis of cute canine monikers comes from Trupanion, a provider of medical insurance for pets. The company looked at its database of 500,000 dogs and crunched the numbers to identify the names that are currently having a moment. (Although some of the names that cracked the top 10 list, like Daisy and Max, have been around for quite some time.)

Interestingly, Luna wasn’t always popular. As Trupanion points out, “Looking back 10 years, Luna was barely a blip on the name game chart … not even cracking the list of top 20 names.” Nor did it appear on ​Banfield Pet Hospital's list of the 10 most popular dog names of 2018.

Often, there's some overlap between popular pet names and baby names. Luna was the 31st most popular baby name for girls in 2018. This is perhaps linked to the popularity of the Harry Potter character Luna Lovegood, as well as the publicity the name has received in recent years from celebrities like John Legend and Chrissy Teigen and Penélope Cruz and Javier Bardem, as both couples named their daughters Luna.

Second on the list of popular puppy names is Bella (its longer form, Isabella, was the fifth most popular baby name for girls last year). Check out the top 10 list below to see if your pooch’s name is trending right now.

1. Luna
2. Bella
3. Charlie
4. Bailey
5. Lucy
6. Cooper
7. Max
8. Daisy
9. Bear
10. Oliver
