There are some new residents at the Tower of London. They're only about 11 inches tall, are very noisy, and eat rats for breakfast, lunch, and dinner. Fortunately, they're also adorable—not to mention protected by legend.
On May 17, the Tower of London announced that their breeding pair of ravens, Huginn and Muninn, had welcomed four healthy chicks, the first born at the Tower since 1989. The ravens are part of an unkindness that's been located at the Tower for centuries as a sort of protective asset. According to legend, the Tower must always have ravens, or both the Tower and the kingdom will fall. It's not exactly clear when the legend began, but according to the Tower, Charles II decreed there must always be six ravens present.
Huginn and Muninn are newer additions, having arrived at the Tower in late 2018, and they weren't expected to breed this spring. So it was a surprise in mid-April when the devoted Tower Ravenmaster, Yeoman Warder Chris Skaife, noticed something exciting going on. "My suspicions were first piqued that we might have a chance of baby chicks when the parents built a huge nest suddenly overnight and then almost immediately the female bird started to sit on it," Skaife said in a Tower press release. On April 23, Skaife noticed the birds flying to the nest with food, but it was only this week he was able to get close enough to see the four healthy chicks. The sight delighted him: "Having worked with the ravens here at the Tower for the last 13 years and getting to know each of them, I feel like a proud father!"
Say hello to our new baby ravens at the Tower of London 👋 These four little chicks are the first to be born here in 30 years. Legend tells us that should the ravens ever leave, the Tower will fall. Now, our future is secured and Chris Skaife @ravenmaster1 is one happy Dad! pic.twitter.com/BirBqM1Oiw— The Tower of London (@TowerOfLondon) May 17, 2019
The chicks have grown quickly, already quadrupling in size since they were born, and eat a diet of quail, rats, and mice the Ravenmaster provides. The raven parents have an egalitarian feeding arrangement: Huginn, the male, preps the food and passes it to Muninn, the female, who feeds it to her tiny chicks.
The plan is for one of the chicks to stay at the Tower and join the rest of the ravens there. "As the ravens started to hatch on the 23 April, St. George’s Day, the raven that will be staying at the Tower will be called George or Georgina in honor of the occasion," the Tower explained in a press release. According to The Telegraph, the breeding program at the Tower kicked off in response to a decline in the number of legal raven breeders in the UK.
The last raven chick born at the Tower was Ronald Raven, born May 1, 1989. In his 2018 book, The Ravenmaster: My Life with the Ravens at the Tower of London, Skaife wrote that "a baby raven looks a bit like a grotesque miniature gargoyle, but then you see them grow and develop ... It really is wonderful."

Last week, scientists aboard a NOAA Ocean Exploration and Research ship in the Gulf of Mexico captured video of an elusive giant squid—the first recorded sighting in U.S. waters. In the 28-second clip, the cephalopod emerges from the blackness of the deep sea and attacks an electronic jellyfish. After wrapping its tentacles around the luminescent bait, the squid loses interest and disappears in the murk. Since ancient times, philosophers and naturalists have puzzled over this rarely seen enigma. There’s plenty we still don’t know about giant squid, but we’ve learned a lot over the past 20 years.
A staggering 10.5 inches across, a squid’s eyeballs lack the jelly-like substance that gives ours their shape. Instead, they’re filled with water, which leaks out once the invertebrate dies. "The eyes collapse. It's like a collapsed plastic bag,” biologist Dan-Eric Nilsson told NPR in 2012.
2. Female giant squid are bigger than males.
On average, female giant squid are around twice the size of males from the tip of their beaks to the ends of their two longest tentacles.
3. Giant squid suckers can leave ugly battle scars.
The giant squid's main enemy is the sperm whale. While under attack, the squid often retaliate by inflicting large, circular wounds, courtesy of the serrated rings around each sucker.
4.The giant squid’s maximum length is about 43 feet.
At least, that’s what the available evidence tells us. Reports of 60- and 70-footers have never been verified scientifically.
5. Instead of a proper tongue, they use a radula.
This organ rests inside their beaks and is covered with seven rows of denticles—sharp, toothy, backwards-pointing protrusions.
6. There may be just one known species.
A genetic analysis in 2013 suggested that Architeuthis duxis the only species of giant squid, as revealed by a comparison of 43 specimens from around the world. The giant squid gene pool seemed abnormally shallow—all 43 subjects were pretty much indistinguishable in this regard. “It’s completely bizarre,” geneticist Thomas Gilbert said. “How can something be global but have so little variation?” Other researchers, however, argue that there may be as many as eight Architeuthis species out there.
7. Giant squid tentacles can regenerate.
One giant squid corpse found in Canada in 1968 had a partially regenerated tentacle. According to a study of the specimen in the Canadian Journal of Zoology, "the regenerated club differed in length and width, and in the size and pattern of suckers, when compared with the normal tentacular arm." Many cephalopods besides squid are capable of this feat, including octopuses.
8. An estimated 4.3 to 131 million get eaten by sperm whales each year.
The squid regularly show up inside sperm whale stomachs. Approximately 360,000 of these mammals swim the oceans. So, if every sperm whale on Earth devoured an average of one giant squid per month, that means 4.3 million would be offed annually.
But some experts think this figure is way too low. Every single day, male whales put away 300 to 400 squid of various species, while females consume an outrageous 700 to 800 squid. Should Architeuthis represent even 1 percent of their diet, then the whales eat 3.6 million daily. That’s 131 million giant squid killed annually.
9. Giant squid may have helped give rise to sea serpent legends.
In one of Moby-Dick’s more memorable chapters, an Architeuthis slithers towards Captain Ahab’s whaleboat. Apparently, Herman Melville wasn’t a fan—Ishmael describes the squid as a “vast, pulpy mass” complete with “innumerable long arms radiating from its center, curling and twisting like a nest of anacondas.” But Melville wasn't alone. Many believe that this predator’s writhing, snake-like limbs have long inspired sea serpent yarns.
10. 20,000 Leagues Under the Sea grossly overestimates the giant squid’s usual weight.
Jules Verne’s 1869 masterpiece remains impressive today: his novel predicted the invention of both scuba tanks and taser guns. But there are still a few gaffes to be found, particularly during the book’s most iconic scene. When hordes of giant squid attack, the narrator, a French professor named Pierre Arronax, estimates that each one must weigh “between four and five thousand pounds.” But as far as modern scientists can tell, the heaviest animals weigh around a ton—although most are less than 1000 pounds.
11. Like all squids, giant squids have three hearts.
A median heart pumps oxygenated blood throughout the body, which it receives from two smaller ones that pump blood through the gills.
12. Architeuthis penises are about a yard long.
Nobody has ever documented a pair of giant squid getting busy. But biologists suspect that males use their sex organs like syringes, injecting sperm into a female’s skin, where she stores the cells until her eggs need fertilizing. When that happens, the mom-to-be pulls them out of storage (though we’re not sure how).
13. The first giant squid photo ever shot was taken inside of a bathroom.
In 1873, Newfoundland minister Moses Harvey acquired a dead Architeuthis which he laid out over his shower curtain rod and preserved for posterity. He’d purchased this specimen for just $10 from a few local fishermen who’d ensnared it with their nets while out in Logy Bay.
14. Giant squid might be cannibals.
Bits and pieces of one Architeuthis showed up in a live giant squid's stomach. But this doesn’t necessarily prove that giant squid dine on one another—some scientists speculate that the squid may have accidentally swallowed a few parts of itself somehow.
15. The Smithsonian has two giant squid on display.
You can see them in the National Museum of Natural History’s Sant Ocean Hall. The pair represents both sexes—here’s a quick look at their 25-foot female (it was probably 36 feet while alive):
16. Their brains are donut-shaped.
But that’s not the weird part. What’s truly bizarre (at least from our mammal-centric perspective) is the fact that its esophagus passes through the hole in the middle of its brain. Giant squids have to be really careful while swallowing, because if a given meal isn’t broken down into small pieces first, it can rub against the brain and cause damage.
17. Before 2004, nobody had ever snapped any pictures of a live one …
History was made by residents of the Ogasawara Islands (located 600 miles south of Japan) on September 30, 2004. Using a line baited with shrimp, zoologist Tsunemi Kubodera and whale-watcher Kyochi Mori attracted an Architeuthis about 2950 feet beneath their vessel. Five hundred still images were then snapped by a submerged camera before the squid took off—leaving behind an 18-foot severed tentacle.
18. … And the world’s first giant squid video didn’t arrive until 2006.
Kubodera would top himself that year when his crew videotaped a young female as they dragged her up to the surface. “We believe this is the first time anyone has successfully filmed a giant squid that was alive,” he said. “Now that we know where to find them, we think we can be more successful at studying them in the future.” Sadly, Kubodera’s prize died during the ordeal.
19. Jellyfish help Architeuthis hunt.
They say the enemy of your enemy is your friend. Certain jellyfish are bioluminescent, which means that they can light themselves up and illuminate the ocean’s inky depths. Predators like giant squid eat many of the fish that hunt jellyfish. So, if a bioluminescent jelly finds itself under attack, it can issue a cry for help by flashing a distress signal, in the hopes that it might attract an even larger carnivore and scare off its assailant. That was the theory behind luring the giant squid with an electronic jellyfish, as seen in the recent NOAA video.
20. It’s not the only monster-sized squid out there.
Meet Mesonychoteuthis hamiltoni, better known as the colossal squid. Though Architeuthis probably exceeds it length-wise, M. hamiltoni is heavier on average, has even bigger eyeballs, and wields swiveling hooks on its tentacles. This isn't a creature you’d want to mess with.
Planning a trip can be stressful no matter the circumstances. When you want to include the family pet in your plans, you have a whole new list of things to worry about, including packing the right equipment, checking your hotel’s pet policy, and making sure your pet meets the travel criteria for the state or country you’re visiting. But if you’re aware of the steps you need to take, traveling with your pet can be a positive experience for all involved. Mental Floss spoke with Dr. Danielle Bernal, a veterinarian with Wellness Natural Pet Food, about what to keep in mind before hitting the road with your furry companion.
1. Keep pets comfortable in a travel crate.
You may be tempted to give your pet plenty of room on long car trips, but giving them a confined space that’s their own is usually the better option. According to Bernal, “It’s often better for the dog, because if they’re crate-trained, that’s their area of security.” It’s safer as well: An animal is much better off in a durable crate than it is sliding around untethered in the backseat of a car.
2. Don’t fill your pet's crate with toys.
Giving your pet lots of toys to play with at home is a good thing—but on long car trips it's a different story. Packing every toy your pet loves into their crate takes up what little room they have to themselves. If the crate is too full, it can be impossible for them to move around and adjust their position. “Yes, you want them to be comfortable, but also you don’t want to fill that crate up,” Bernal says. “So almost less is more.”
3. Make sure you have all the correct paperwork.
If you’re planning a long trip with your pet, you won’t get very far without the right paperwork. Many places require incoming pets to have an up-to-date health certificate signed by an accredited veterinarian. Before signing the documents, vets will confirm that your pet is healthy and up-to-date on all vaccinations required by the receiving state or country. If you’re flying, contact the airline to see if any other special paperwork is required to transport your animal.
4. Make it easier to find your pet if they get lost.
An unfamiliar location miles away from home is the worst place to lose your pet. Before your trip, make sure they’re easy to find in case the worst happens. Implanting a microchip under your dog or cat’s skin will make them trackable no matter where in the country they wander off to. If you’re not willing to commit to that procedure, at least make sure the contact information on their tags is up-to-date—that way, they're more likely to be returned to satefy if someone finds them.
5. Skip a meal on travel days.
No matter how accommodating you are to your pet, some anxiety on their part is inevitable. Bernal says a common symptom of this is stress diarrhea—which is the last thing pet owners want to deal with on a long car or plane ride. Even if your pet doesn't seem stressed before the trip, plain old motion sickness can upset your animal’s stomach rather quickly. Bernal recommends feeding them less than you usually would prior to traveling to avoid future accidents: “If you have a pet you know has those sensitivities, I would keep their tummy empty. It will be good for the pet and it will be nicer for everyone in the car too.” That doesn’t mean you should starve your pet if they’re begging for food; just skip the last meal you would normally feed them before beginning your journey.
6. Keep your pet hydrated.
Without regular access to water whenever they need it, pets can get easily dehydrated when traveling. Keep this in mind when traveling and pack extra water for your four-legged passenger. Allowing animals to self-regulate their water intake, perhaps by attaching a bowl to the inside of their crate, is ideal, but if that’s not possible, stop frequently to give them a chance to drink. Another way to keep them feeling good is to feed them wet food instead of dry; according to Bernal, the water content in wet food can help hydrate pets.
7. keep them occupied with a toy.
If you can only give your pet one toy on a long trip, choose something that will keep them busy for as long as possible. Bernal recommends puzzle dog toys like those you’ll find from the pet brand Kong. When your dog is preoccupied on reaching the treat inside the toy, it's harder for them to focus on anything else—including the stress of traveling to a new place.
8. Never leave your pet in a car alone.
Hopefully this is common sense for most pet parents, but Bernal emphasizes that this is the most important thing to remember when traveling with an animal—especially during the summer months. “Don’t leave them in a locked car,” she says. “It takes seven minutes for them to basically move into a situation where it becomes fatal.” It doesn’t matter if you crack a window or if you’re only stepping out of your car for a few minutes. If it’s a hot day, dogs should never be left alone in a vehicle. “We need to make sure that all pet parents are aware of that,” Bernal says.
9. Choose pet-friendly accommodations.
You may love your pet, but that doesn’t mean the owner of the hotel or Airbnb where you’re staying will love them, too; be mindful of this when booking accommodations for your trip. There are plenty of hotels that offer perks for pet owners, like doggie daycare, but even if a place doesn’t advertise their pet policy, it doesn’t hurt to call and ask (or simply confirm what you're reading online so that there are no surprises when you arrive).
10. Make your travel destination feel like home.
Your pet’s crate may not be the best place for all their toys, but that doesn’t mean you shouldn’t pack them when going on vacation. Bringing their favorite items from home can make pets feel more at ease when they arrive at an unfamiliar destination. “Pack things that are familiar to them, so when they arrive at a new spot they’re like: ‘Ok, I feel a lot more comfortable,’” Bernal says. “It helps with their anxiety.” And you shouldn’t stop at toys: Packing their bed, bowl, and blanket can have the same calming effect.
11. Know when it's best to leave your pet at home.
Not every vacation is improved by bringing your pet along. If you plan on spending most of your trip in places that don’t allow animals, like museums, restaurants, and theme parks, it may be best to leave your pet at a kennel or with a sitter or trusted friend. Even if the vacation is pet-friendly, it may not be a good fit for an animal that’s especially anxious. “If you have a nervous dog, he’s actually going to be happier in his home if someone just comes in and feeds him,” Bernal says. Your pet will forgive you for having fun without them.
