25 Delicious Facts About Lobsters

We cracked open America's favorite crustacean, Homarus americanus, to plate the delicious facts hiding inside. Bob Bayer, head of the University of Maine’s Lobster Institute, helps us out.

1. If you cut a lobster, does it not bleed? Yes, of course—but it doesn't look like you'd expect. Lobster blood is colorless until exposed to oxygen, at which point it turns blue.

2. Typically, lobsters are a mottled brown, but genetic mutations can create red, blue, calico, and even albino lobsters. Heat denatures the proteins in the lobsters’ shells, releasing astaxanthin, which turns their shells bright red when they’re cooked.

3. Every time they molt—splitting their shells along the seam in the carapace—lobsters increase 20 percent in size. Young lobsters molt several times a year, but after they hit one pound, they start molting annually. After finding a soft place to hide, “they shed every part of the hard material, including the lining of the intestine,” Bayer says. "When the lobster comes out of its old shell, it’s all wrinkly. Its new shell is softer than your skin. If you take that lobster out of water, the claws will fall off; it doesn’t have the mechanical strength to keep the claws on." Then they eat their old shells for the calcium and phosphorus.

4. Freshly molted lobsters are called shedders.

5. The warmer the water, the faster lobsters grow.

6. Lobsters have three pairs of antennae, the largest of which is used for tactile sensing. "If a lobster’s going to go into a hole, for example, it’ll wave those large antennae around, sort of feel the hole, and then determine if it can fit, and then it’ll back in and hide," Bayer says. The two smaller pairs are chemosensory, helping the lobster find its food by sensing dissolved substances in the water, "a combination of our sense of taste and smell in one function,” according to Bayer.

7. The bigger claw is called the crusher claw, and lobsters use it to break up clams, crabs, and sea urchins. The cutter claw is used for tearing. “Some good-sized lobsters can raise a pressure closing strength of 100 pounds per square inch,” Bayer says. “Most of them are less than that, but it’s still a good amount of pressure.” If a lobster loses one of its claws or walking legs, the limb will regenerate. "If you’ve got a wound around the time that lobster is molting, you sort of get mixed biochemical signals, so you might end up with a duplicate of something," Bayer says. "You might get, say, two thumbs sticking out of the same claw."

8. Lobsters walk forward, but if they need to quickly get away, they propel themselves backward by pumping their tails. Females have broader tails than males so they can hold eggs there.

9. These crustaceans can’t see clear images, but their compound eyes are sensitive to light. Severing the eyestalk—which also serves as the lobster's hormonal center—will cause it to molt. And eyes don't grow back.

10. Lobsters use the front two legs—which are studded with chemosensory hairs—to put food into their mouths. “It almost looks like a squirrel eating,” Bayer says. The food goes into the stomach, where the gastric mill—made up of three teeth-like structures—grinds it up. Next, the food travels through the tomalley—a.k.a. the green thing you scrape off your meat. It’s the lobster’s main digestive tract: a small intestine, pancreas, and liver in one—and it’s a delicacy!

11. Lobsters aren’t scavengers; in fact, they feed on a large variety of live things, including other lobsters, marine worms, clams, mussels, and crabs in addition to bait (which is most often salted herring).

12. It takes a lot of herring to catch a lobster: "It averages about a pound of herring per pound of lobster that’s caught," Bayer says. "It’s expensive. It may be more than we need. We actually had a student who looked at this, and she found that you could use less and catch the same amount of lobster. But old habits die hard."

13. Fin-like structures called swimmerets help lobsters circulate water inside their shelters; females also use them to carry eggs.

14. Lobsters pee out of their faces. The urine comes from antennal glands located near the antennae. "They're greenish brown spots," Bayer says. "They actually look like two pieces of snot—that’s the best way to describe them. You'd have to open them up to see them." Peeing at each other is part of both fighting and courtship.

15. Speaking of courtship: In lobsters, it's kind of complicated. To woo a dominant male—who will have previously spent his time beating up her and all of the other lobsters in his neighborhood—the female heads to his shelter a number of times and pees pheromone-laced urine into it, which helps him relax. Because lobsters are cannibals, the pheromone is telling him two things: “It’s time to breed" and "Don’t eat me!”

Eventually, when he is sufficiently wooed, she'll move into his shelter and molt, at which point he uses the first pair of swimmerets—which, in males, are hard and bone-like and called gonopods—to transfer sperm to her. She'll stay in his shelter for another 10 days or so while her new shell hardens. Then she's back to her own life, and it's time for a new female to woo the male.

16. She stores the semen in a receptacle between her walking legs for six to nine months before she extrudes eggs, which then sit on her tail for another six to nine months. "When they’re immature, they’re very dark," Bayer says. "As they’re getting ready to hatch, these larvae, you can see the eyes." 

17. A lobster that's a pound and a half might carry 8000 to 10,000 eggs, which are kept in place by glue created in her cement glands. "The bigger they are, the more eggs they have," Bayer says. "You might have 30,000 or 40,000 on a really big lobster." If you’re eating lobster and find bright red stuff, that’s unextruded eggs—also known as roe.

18. When a fisherman traps a female lobster carrying eggs, he puts a V-notch in her tail. This tells other fishermen that she's a breeding female whether she has eggs or not, and should be thrown back. "They’re protected as long as that notch is present," Bayer says. "You're protecting your breeding population. If you think about it, it’s sensible, because you’re going to have your classes that don’t settle well, that don’t have good survival, but you’ve got this huge root stock that’s out there, so that the next year it can come back."

19. "When lobsters first hatch, they float—they float for the first couple of weeks," Bayer says. Some scientists call those floaters superlobsters, because they can swim forward in the water with their claws outstretched by beating the swimmerets under their tails. After this phase, they settle on the bottom. "Those that settle to the bottom, many of them will survive," Bayer says, "and it’s a good measure of what the upcoming stock is."

20. By the way: Despite what Phoebe from Friends believed, lobsters aren't monogamous. "Sometimes they'll have multiple parentage," Bayer says.

21. Fishermen used to guess at a lobster's age based on its size. Scientists only recently discovered an accurate way to determine a lobster's age: dissecting it and counting the rings in the eyestalk and gastric mill—similar to the way we calculate a tree's age.

22. The largest lobster ever recorded was caught near Nova Scotia in 1977 and weighed 44 pounds!

23. Science has shown that lobsters can recognize each other. Researchers at Woods Hole Oceanographic Institution set up an experiment where two crustaceans fought each other in a ring. Later, when they tried to have those same two lobsters fight again, the one that lost the first time recognized the winner and backed down immediately. "It wasn't just that the loser lobster had become a sissy or something," Trevor Corson, author of The Secret Life of Lobsters, told National Geographic. "When matched with a new lobster, he fought ferociously. So he was recognizing that previous lobster. They blindfolded him, and it didn't make a difference. So we get back to this pissing-in-each-other's-faces thing. [The scientists] catheterized a lobster with little tubes attached to its face and collected urine during combat. It turned out that without the urine in the water, the lobsters couldn't recognize each other." The losing lobster would recognize the winner for up to a week.

24. Can lobsters and other crustaceans feel pain? Scientists have gone back and forth on this; some recent research suggests that they probably do, while another study, published in 2005, says they don't. "There can be no absolute answer," Bayer says, though he's in the "no pain" camp. "They sense their environment, but don’t have the intellectual hardware to process pain. [If you look at] the nervous system of a lobster next to a grasshopper, and what’s notable is that the nervous system is so primitive that there isn’t really much to it. We argue that there is no brain and no ability to process pain. They do respond to their environment, and they sense that it’s not right for them. If they sense warmth or even chemicals in their environment, they’ll try to avoid them, those things that are noxious." Some suggest that the most humane way to cook a lobster is to start by putting it in fresh cold water or the freezer—both of which essentially puts it to sleep—before dropping it in the pot. (The "scream," by the way, isn't a scream at all, but steam escaping from their shells.)

25. According to Bayer, "Anything that kills insects can kill a lobster," and lobsters are extremely sensitive to insecticides, even at parts-per-billion concentration: "They’re so sensitive that, if you’ve got a room with a lobster tank, and you take an insecticide and you give it a five-second spray at the end of the room, it's likely that all those lobsters would be dead by the end of the day," he says. So we might want to think about what we're dumping into our oceans.


15 Delicious Facts About Pizza Hut

For more than 60 years, Pizza Hut has been slinging hot, cheesy pies to hungry consumers all over the world. (There are more than 16,000 locations worldwide.) Whether you're a meat lover or vegetarian, here are 15 things you should know about the popular pizza chain.

1. It was founded by two brothers who were still in college.

Dan and Frank Carney borrowed $600 from their mother in 1958 to open a pizza place while attending Wichita State University. The name was inspired by the former bar that they rented to open their first location.

2. Pizza Hut franchising was almost instant.

A year after the first location opened in Wichita, Kansas, the Carney brothers had already incorporated the business and asked their friend Dick Hassur to open the first franchise location in Topeka, Kansas. Hassur, who had previously gone to school and worked at Boeing with Dan Carney, was looking for a way out of his insurance agent job. He soon became a multi-franchise owner, and worked to find other managers who could open Pizza Huts across the country.

Once, when a successful manager of a Wichita location put in his notice, Hassur was sent in to convince the man to stay. That manager happened to be Bill Parcells, who had resigned his Pizza Hut job in order to take his first coaching job at a small Nebraska college. Of course, he later went on to coach numerous NFL teams, including leading the New York Giants to two Super Bowl victories. "I might have been wrong there," Hassur said of trying to convince Parcells his salary would be better as a manager than as a coach, "but I'm sure he'd have been successful with Pizza Hut, too."

3. There was a mascot in the early days.

Before the iconic red roof logo was adopted in 1969, Pizza Hut had a mascot named Pizza Pete who also served as its logo. The mustachioed cartoon man wore a chef’s hat, neckerchief, and an apron while serving up hot meals to hungry customers. Pizza Pete was still used throughout the 1970s on bags, cups, and advertisements, but was eventually phased out.

4. Pizza Hut perfume was a thing that existed.

It was announced late in 2012 that Pizza Hut had plans to release a limited edition perfume that smelled like "fresh dough with a bit of spice." One hundred fans of the Pizza Hut Canada Facebook page won bottles of the scent, and another promotion around Valentine's Day gave American pizza lovers a chance to own the fragrance via a Twitter contest. The packaging for the perfume resembled mini pizza boxes, and a few later surfaced on eBay for as much as $495.

5. They struck gold with the Teenage Mutant Ninja Turtles.

When a group of crime fighting turtles that love pizza become huge pop culture icons, it's a no-brainer that a pizza company should do business with them. Domino's was featured in the first Teenage Mutant Ninja Turtles film in 1990, but ads for Pizza Hut were included on VHS when the film hit home video. Pizza Hut also reportedly spent around $20 million on marketing campaigns for the Turtles during the 1990 "Coming Out of Their Shells" concert tour and album release. The partnership continued all the way up to the 2014 release of Michael Bay's Teenage Mutant Ninja Turtles.

6. Pizza Hut Easy-Bake ovens were also real.

Children of the '70s were lucky enough to own small toy ovens shaped like the restaurant in which they could bake tiny little Pizza Hut pizzas under a 60-watt light bulb.

7. Their vintage commercials are star-studded.

An 11-year-old Elijah Wood got his start flinging potato salad at his co-star; Ringo Starr and the Monkees marveled at the stuffed-crust pizza; and former Soviet statesman Mikhail Gorbachev had a very odd, political pizza pitch, appearing along with his young granddaughter in a Russian Pizza Hut (though the ad was not set to run in Russia).

8. The Book It! program is 35 years old.

In 1984, Pizza Hut kicked off the BOOK IT! program, an initiative to encourage children to read by rewarding them with "praise, recognition and pizza." It was such a success that First Lady Barbara Bush threw a reading-themed pizza party at the White House in 1989. The program is now the "longest-running corporate-supported reading program in the country" and has reached over 60 million children.

9. They were early to the pan pizza create.

Pizza Hut introduced pan pizza in 1980, nine years before their competition, Domino's, added the style to their menu. In 1983, they introduced personal pan pizzas, which are still the coveted prize of the BOOK IT! program and the only pizza option at smaller Pizza Hut cafes (like those inside Target stores).

10. They were also early to online ordering.

In 1994, Pizza Hut and The Santa Cruz Operation created PizzaNet, an ahead-of-its-time program that allowed computer users to place orders via the internet. The Los Angeles Times called the idea "clever but only half-baked" and "the Geek Chic way to nosh." And, the site is still up and running! Seriously, go ahead and try to order.

11. Pizza Hut pizza has been to space ...

In 2001, Pizza Hut became the first company to deliver pies into space. Before being sealed and sent to the International Space Station, the pizza recipe had to undergo "rigorous stabilized thermal conditions" to make sure that it would be still be edible when it got there. Pizza Hut also paid a large, unspecified sum (but definitely more than $1 million) to have a 30-foot-wide ad on a rocket in 1999.

12. … but not to the Moon.

In 1999, Pizza Hut's then-CEO Mike Rawlings (and current Mayor of Dallas) told The New York Times that an earlier idea for space marketing was for the logo to be shown on the moon with lasers. But once they started looking into it, astronomers and physicists advised them that the projected image would have to be as large as Texas to be seen from Earth—and the project would also have cost the company hundreds of millions of dollars. Better to stick with Super Bowl ads.

13. They once offered pizza engagement packages.

What's the perfect way to pop the big question? In 2012, Pizza Hut suggested that grooms- (or brides-) to-be order the engagement party package that included a $10 dinner box, a limo, a ruby ring, fireworks, flowers, and a photographer, all for $10,010. In keeping with the theme, only 10 of the packages were offered. But, to be clear—if you bought a Pizza Hut engagement package, you would have spent $10 on food and approximately the cost of a wedding on the proposal.

14. Pizza Hut accounts for three percent of U.S. cheese production.

With all those locations and cheese-stuffed crusts, Pizza Hut needs a lot of dairy. The company uses over 300 million pounds of cheese annually and is one of the largest cheese buyers in the world. To make that much cheese, 170,000 cows are used to produce an estimated 300 billion gallons of milk. Something to think about the next time you order an Ultimate Cheese Lover's pizza with extra cheese.

15. There are a lot of repurposed Pizza Hut locations.

Franchise locations of companies are not always successful, and when they close, the buildings are often left untouched by their new owners rather than being demolished and replaced. Because the hut-shaped stores have become synonymous with the company, their former locations are easy to spot. The blog "Used to Be a Pizza Hut" has an interactive map of more than 500 ex-huts submitted by people all over the world. There is also a successful Kickstarter-funded photo book—called Pizza Hunt—documenting the "second lives" of the restaurants.

5 Fast Facts About Sake Dean Mahomed

Today's Google Doodle will be many people's first introduction to Sake Dean Mahomed, a noted traveler, surgeon, author, and entrepreneur who was born in Patna, India in 1759. Though he's been left out of many modern history books, Mahomed left a profound impact on Western culture that is still being felt today.

In honor of the 225th anniversary of the publication of his first book—The Travels of Dean Mahomed, a Native of Patna in Bengal, Through Several Parts of India, While in the Service of the Honorable the East India Company—on January 15, 1794, here are some facts about the figure.

1. He was the first Indian author to publish a book in English.

In 1794, Sake Dean Mahomed published The Travels of Dean Mahomet, an autobiography that details his time in the East India Company's army in his youth and his journey to Britain. Not only was it the first English book written by an Indian author, The Travels of Dean Mahomet marked the first time a book published in English depicted the British colonization of India from an Indian perspective.

2. His marriage was controversial.

While studying English in Ireland, Mahomed met and fell in love with an Irish woman named Jane Daly. It was illegal for Protestants to marry non-Protestants at the time, so the pair eloped in 1786 and Mahomed converted from Islam to Anglicanism.

3. He opened the England's first Indian restaurant.

Prior to Sake Dean Mahomed's arrival, Indian food was impossible to find in England outside of private kitchens. He introduced the cuisine to his new home by opening the Hindoostane Coffee House in London in 1810. The curry house catered to both British and Indian aristocrats living in the city, with "Indianised" versions of British dishes and "Hookha with real Chilm tobacco." Though the restaurant closed a few years later due to financial troubles, it paved the way for Indian food to become a staple of the English food scence.

4. He brought "shampooing" to Europe.

Following the failure of his restaurant venture, Mahomed opened a luxury spa in Brighton, England, where he offered Eastern health treatments like herbal steam baths and therapeutic, oil-based head massages to his British clientele. The head massages eventually came to be known as shampoo, an anglicized version of the Hindi word champissage. Patrons included the monarchs George IV and William IV, earning Mahomed the title shampooer of kings.

5. He wrote about the benefits of spa treatments.

Though The Travels of Dean Mahomet is his most famous book, Mahomed published another book in English in 1828 called Shampooing; or, Benefits Resulting from the Use of the Indian Medicated Vapour Bath.
