You already know they’re cute, compact, and smart. But there’s a lot more to these beloved little dogs that you might not know. 

1. THERE ARE TWO DISTINCT BREEDS OF CORGIS.

There are two types of Welsh corgis: the Pembroke Welsh corgi and the Cardigan Welsh corgi. They are considered two entirely different breeds because they come from different ancestors. Their remarkable resemblance is a result of crossbreeding in the 19th century.   

If you’re trying to tell the two breeds apart, the most notable difference is that the Pembroke does not have a tail. On top of a tail, Cardigan Welsh corgis also have rounded ears, while Pembrokes generally have pointy ears. 

2. THE CARDIGAN WELSH CORGI IS THE OLDER BREED.

A warrior tribe of Celts brought the corgis in their aboriginal form to Cardiganshire, Wales around 1200 BCE, which means corgis have been in Wales for over 3000 years. This early breed was a member of the Teckel family of dogs that went on to include the dachshund. 

3. PEMBROKE WELSH CORGIS HAVE A CONSIDERABLE HISTORY AS WELL.

Although no one knows for sure, most agree that the Pembroke Welsh corgi dates back to 1107 CE when Flemish weavers migrated to Wales. The Spitz-type dog bred with the original Cardigan corgis to produce the Pembroke Welsh corgis we know today. 

4. THE KENNEL CLUB ORIGINALLY LUMPED THE TWO BREEDS TOGETHER.

The two types of corgis were registered as one in 1925, leading to a lot of stress among breeders. Often a judge would favor one breed over the other, which would lead to controversies at dog shows. After nearly a decade of (pretty adorable) strife, the breeds gained separate recognition in 1934. 

5. CORGIS WERE ORIGINALLY USED AS HERDERS.

The Welsh used the short dogs as herders as early as the 10th century. In those days, pastures were considered common land, so there were no fences. In order to keep a farmer’s cattle together and separated from other herds, corgis would nip at their legs to herd them. Because of their closeness to the ground, corgis had easy access to the cows’ ankles and were difficult targets of the retaliatory kicks of cattle. 

6. ACCORDING TO WELSH LEGEND, FAIRIES RIDE THEM.

Some say that the corgi is an “enchanted dog” favored by fairies and elves. At night the magical creatures would use the dogs to pull their carriages and be their steeds in battle. According to legend, the markings on a corgi’s coat suggest the faint outline of a saddle and harness. 

7. THE ROYAL FAMILY LOVES THE PEMBROKE WELSH CORGI.

Queen Elizabeth II has had more than 30 corgis in her lifetime. Though her last two corgis—Whisper and Willow—have both recently passed away, she does still have two dorgis (corgi/dachshund mixes) named Candy and Vulcan.

The Queen met her first corgi when King George VI brought a male pooch home from a kennel in 1933. Named Dookie, the dog was an immediate hit with the future queen and her sister, Princess Margaret. 

After a second corgi named Jane entered the picture, the canine couple had a litter of puppies, two of which were kept. The Queen received another dog named Susan for her 18th birthday—from there, the collection of corgis really gained momentum. Some of the royal corgis bred with Princess Margaret’s dachshund Pipkin to create dorgis.

8. CORGIS WERE USED TO PREDICT PRINCESS CHARLOTTE'S NAME.

In the spring of 2015, when Prince William and Kate Middleton were awaiting the birth of their second child, people are already taking bets on the name. Gambling company Ladbrokes used corgis in an attempt to predict what the name would be. The company’s ad featured 10 corgis wearing vests with different names in a race to predict what the name of the child would be. The corgi sporting the name Alexandra won the race. Princess Charlotte was born on May 2, 2015.

9. CORGI MEANS "DWARF DOG" IN WELSH.

According to the Oxford English Dictionary, cor means dwarf and gi means dog.  

10. SOUTHERN CALIFORNIA HOSTS A ENORMOUS CORGI MEETUP.

SoCal Corgi Beach Day started as a humble meet-up event at Huntington Beach in 2012. The first event attracted just 15 dogs; the last one had more than 1100 corgis in attendance. The event happens three times a year.

10 Juicy Facts About Leeches

Ian Cook

Leeches get a bad rap, but they’re actually pretty cool once you get to know them—and we're finding out more about them, even today. Recently, a team led by Anna Phillips, curator of parasitic worms at the Smithsonian National Museum of Natural History, discovered a new species of medicinal leech (pictured above) in a Maryland swamp. We asked parasite expert and curator at the American Museum of Natural History Mark E. Siddall to share some surprising facts about the worms we love to hate. 

1. Not all leeches suck blood.

Hematophagous, or blood-feeding, species are only one type of leech. “The vast majority of species are [hematophagous],” Siddall tells Mental Floss, “but it depends on the environment. In North America, there are probably more freshwater leeches that don’t feed on blood than there are blood-feeders.” And even among the hematophagous species, there are not too many who are after you. “Very few of them are interested in feeding on human blood,” Siddall says. “Certainly they’ll do it, if they’re given the opportunity, but they’re not what they’re spending most of their time feeding on.” 

2. Leeches are everywhere.

“Every continent on the planet has leeches, with the exception of Antarctica,” Siddall says. “And even then there are marine leeches in Antarctic waters.” Humans have co-existed with leeches for so long, according to Siddall, that just about every language has a word for leech. 

3. Leeches have made a comeback in medicine.

Bloodletting for bloodletting’s sake has fallen out of favor with Western physicians, but that doesn’t mean medicinal leeches are enjoying a cushy retirement. Today, surgeons keep them on hand in the operating room and use them as mini-vacuums to clean up blood. “That is a perfectly sensible use of leeches,” Siddall says. Other uses, though, are less sensible: “The more naturopathic application of leeches in order to get rid of bad blood or to cure, I don’t know, whatever happens to ail you, is complete hooey,” he says. How on Earth would leeches take away bad blood and leave good blood? It’s silly.” 

4. Novelist Amy Tan has her own species of leeches.

Land-based leeches made an appearance in Tan’s 2005 book Saving Fish from Drowning, a fact that instantly put the author in leech researchers’ good graces. “There are not a lot of novels out there with terrestrial leeches in them,” Siddall says. So when he and his colleagues identified a new species of tiny terrestrial leeches, they gave the leech Tan’s name. The author loved it. “I am thrilled to be immortalized as Chtonobdella tanae,” Tan said in a press statement. “I am now planning my trip to Queensland, Australia, where I hope to take leisurely walks through the jungle, accompanied by a dozen or so of my namesake feeding on my ankles.”

5. Leeches can get pretty big.

The giant Amazon leech (Haementeria ghilianii) can grow up to 18 inches and live up to 20 years. And yes, this one’s a blood-feeder. Like all hematophagous species, H. ghilianii sticks its proboscis (which can be up to 6 inches long) into a host, drinks its fill, and falls off. Scientists thought the species was extinct until a zoologist found two specimens in the 1970s, one of whom he named Grandma Moses. We are not making this up.

6. Leeches make good bait.

Many walleye anglers swear by leeches. “A leech on any presentation moves more than other types of live bait," pro fisher Jerry Hein told Fishing League Worldwide. "I grew up fishing them, and I think they're the most effective live bait around no matter where you go." There’s an entire leech industry to provide fishers with their bait. One year, weather conditions kept the leeches from showing up in their typical habitats, which prevented their collection and sale. Speaking to CBS news, one tackle shop owner called the absence of leeches “the worst nightmare in the bait industry.”

7. Leech scientists use themselves as bait.

Siddall and his colleagues collect and study wild leeches. That means hours of trekking through leech territory, looking for specimens. “Whether we’re wandering in water or traipsing through a bamboo forest,” Siddall says, “we are relying on the fact that leeches are attracted to us.” Do the leeches feed on them? “Oh my god, yes. We try to get them before they feed on us … but sometimes, obviously, you can’t help it.”

8. Leech sex is mesmerizing.

Like many worms, leeches are all hermaphroditic. The specifics of mating vary by species, but most twine themselves together and trade sperm packets. (The two leeches in the video above are both named Norbert.)

9. Some leech species make surprisingly caring parents. 

“There’s a whole family of leeches that, when they lay their eggs, will cover them with their own bodies,” Siddall says. “They’ll lay the eggs, cover them with their bodies, and fan the eggs to prevent fungus or bacteria from getting on them, and then when the eggs hatch, they will attach to the parent. They’re not feeding on the parent, just hanging on, and then when the parent leech goes to its next blood meal it’s carrying its offspring to its next blood meal. That’s pretty profound parental care, especially for invertebrates.”

10. You might be the next to discover a new leech species. 

Despite living side-by-side with leeches for thousands of years, we’ve still got a lot to learn about them. Scientists are aware of about 700 different species, but they know there are many more out there. “I’ll tell you what I wish for,” Siddall says. “If you ever get fed on by a leech, rather than tearing off and burning it and throwing it in the trash, maybe observe it and see if you can see any color patterns. Understand that there’s a real possibility that it could be a new species. So watch them, let them finish. They’re not gonna take much blood. And who knows? It could be scientifically useful.”

Fish Tube: How the 'Salmon Cannon' Works and Why It's Important

If you’ve been on the internet at any point in the past week, you’ve certainly come across footage of wildlife conservationists stuffing salmon into a giant plastic tube and shuttling them over obstacles. It’s so bizarre—even by the already loose standards of the web—that it briefly ignited discussions over fish welfare, its purpose, and the seeming desire of people to be similarly transported through a pneumatic tunnel into a new life.

Naturally, the “salmon cannon” has a mission beyond amusing the internet. The system was created by Whooshh Innovations, a company that essentially adopted the same kind of transportation system featuring pressurized tubing that's used in banking. Initially, the system was intended to transport fruit over long distances without bruising. At some point, engineers figured they could do the same for fish.

The fish payload is secured at the entrance of the tube—acceptable species can weigh up to 34 pounds—and moves through a smooth, soft plastic tube that conforms to their body shape. Air pressure behind them keeps them moving. The fish are jettisoned between 16 and 26 feet per second to a new location, where they emerge relatively unscathed. Because there’s no need for a water column, the tubing can cover most terrain at virtually any height.

The tubing solution is a human answer to a human problem: dams. With fish largely confined to still bodies of water thanks to dams and facing obstacles swimming upstream to migrate and spawn, fish need some kind of assistance. In the past, “fish ladders” have helped fish move upstream by providing ascending steps they can flop on, but not all fish can navigate such terrain. Another system, trapping and hauling fish like cargo, results in disoriented fish who can even forget how to swim. The Whooshh system, which has been in used in Washington state for at least five years, allows for expedient fish export with an injury rate as little as 3 percent, although study results have varied.

The video features manual insertion of the fish. In the wild, Whooshh counts on fish making semi-voluntary entries into the tubing. Once they swim into an enclosure, they’re curious enough about the tube to go inside.

If all goes well, the system could help salmon be reintroduced to the Upper Columbia River in Washington, where the population has been depleted by dams. Testing of the device there is awaiting approval from the U.S. Army Corps of Engineers.
