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.


The History Behind 10 Thanksgiving Dishes

Halloween is for candy comas, and on Independence Day we grill, but no holiday is as completely defined by its cuisine as Thanksgiving. No matter what part of the country you're in, it's a safe bet that at least a few of the below dishes will be making an appearance on your table this week. But what makes these specific entrees and side dishes so emblematic of Thanksgiving? Read on to discover the sometimes-surprising history behind your favorite fall comfort foods.

1. Turkey

Turkey has become so synonymous with Thanksgiving that most of us probably imagine the pilgrims and Wampanoag tribe of Native Americans chowing down on a roast bird in 1621. Although we don't know the exact menu of that first Plymouth Colony feast, a first-person account of the year's harvest from governor William Bradford does reference "a great store of wild turkeys," and another first-person account, from colonist Edward Winslow, confirms that the settlers "killed as much fowl as … served the company almost a week." However, culinary historian Kathleen Wall believes that, although turkeys were available, it's likely that duck, goose, or even passenger pigeons were the more prominent poultry options at the first Thanksgiving. Given their proximity to the Atlantic, local seafood like oysters and lobsters were likely on the menu as well.

As the holiday grew in popularity, however, turkey became the main course for reasons more practical than symbolic. English settlers were accustomed to eating fowl on holidays, but for early Americans, chickens were more valued for their eggs than their meat, and rooster was tough and unappetizing. Meanwhile, turkeys were easy to keep, big enough to feed a whole family, and cheaper than ducks or geese. Even before Thanksgiving was recognized as a national holiday, Alexander Hamilton himself remarked that "No citizen of the U.S. shall refrain from turkey on Thanksgiving Day." The country followed his advice: according to the National Turkey Federation, 88 percent of Americans will eat turkey in some form on Thanksgiving Day—an estimated 44 million birds!

2. Stuffing

Stuffing would have been a familiar concept to those early settlers as well, although their version was likely quite different from what we're used to. We know that the first Plymouth colonists didn't have access to white flour or butter, so traditional bread stuffing wouldn't have been possible yet. Instead, according to Wall, they may have used chestnuts, herbs, and chunks of onion to flavor the birds, all of which were already part of the local fare. Centuries later, we're still stuffing turkeys as a way to keep the bird moist through the roasting process and add extra flavor.

3. Cranberries

Like turkeys, cranberries were widely available in the area, but cranberry sauce almost certainly did not make an appearance at the first Thanksgiving. Why not? The sugar reserves the colonists would have had were almost completely depleted after their long sea journey, and thus they didn't have the means to sweeten the terrifically tart berries.

So how did cranberries become such an autumnal staple? For starters, they're a truly American food, as one of only a few fruits—along with Concord grapes, blueberries, and pawpaws—that originated in North America. They grow in such abundance in the northeast that colonists quickly began incorporating cranberries into various dishes, such as pemmican, which mixed mashed cranberries with lard and dried venison. By the Civil War, they were such a holiday staple that General Ulysses S. Grant famously demanded his soldiers be provided cranberries for their Thanksgiving Day meal.

4. Mashed Potatoes

Potatoes weren't yet available in 17th-century Plymouth, so how did mashed potatoes become another Thanksgiving superstar? The answer lies in the history of the holiday itself. In America’s earliest years, it was common for the sitting president to declare a "national day of thanks," but these were sporadic and irregular. In 1817, New York became the first state to officially adopt the holiday, and others soon followed suit, but Thanksgiving wasn't a national day of celebration until Abraham Lincoln declared it so in 1863.

Why did Lincoln—hands full with an ongoing war—take up the cause? Largely due to a 36-year campaign from Sarah Josepha Hale, a prolific novelist, poet, and editor, who saw in Thanksgiving a moral benefit for families and communities. In addition to her frequent appeals to officials and presidents, Hale wrote compellingly about the holiday in her 1827 novel Northwood, as well as in the womens' magazine she edited, Godey's Lady's Book. Her writing included recipes and descriptions of idealized Thanksgiving meals, which often featured—you guessed it—mashed potatoes.

5. Gravy

Despite a dearth of potatoes, it's likely that some type of gravy accompanied the turkey or venison at the earliest Thanksgiving gatherings. The concept of cooking meat in sauce dates back hundreds of years, and the word "gravy" itself can be found in a cookbook from 1390. Because that first celebration extended over three days, Wall speculates: "I have no doubt whatsoever that birds that are roasted one day, the remains of them are all thrown in a pot and boiled up to make broth the next day." That broth would then be thickened with grains to create a gravy to liven day-old meat. And, if Wall's correct, that broth sounds suspiciously like the beginning of another great Thanksgiving tradition: leftovers!

6. Corn

Corn is a natural symbol of harvest season—even if you're not serving it as a side dish, you might have a few colorful ears as a table centerpiece. We know that corn was a staple of the Native American diet and would have been nearly as plentiful in the 17th century as today. But according to the History Channel, their version would have been prepared quite differently: corn was either made into a cornmeal bread or mashed and boiled into a thick porridge-like consistency, and perhaps sweetened with molasses. Today, we eat corn in part to remember those Wampanoag hosts, who famously taught the newcomers how to cultivate crops in the unfamiliar American soil.

7. Sweet Potatoes

In the midst of so many New England traditions, the sweet potatoes on your table represent a dash of African-American culture. The tasty taters originally became popular in the south—while pumpkins grew well in the north, sweet potatoes (and the pies they could make) became a standard in southern homes and with enslaved plantation workers, who used them as a substitution for the yams they'd loved in their homeland. Sweet potato pie was also lovingly described in Hale's various Thanksgiving epistles, solidifying the regional favorite as a holiday go-to. More recently, some families further sweeten the dish by adding toasted marshmallows, a love-it-or-hate-it suggestion that dates to a 1917 recipe booklet published by the Cracker Jack company.

8. Green Bean Casserole

Beans have been cultivated since ancient times, but green bean casserole is a decidedly modern contribution to the classic Thanksgiving canon. The recipe you probably know was whipped up in 1955 by Dorcas Reilly, a home economist working in the Campbell's Soup Company test kitchens in Camden, New Jersey. Reilly's job was to create limited-ingredient recipes that housewives could quickly replicate (using Campbell's products, of course). Her original recipe (still available at Campbells.com), contains just six ingredients: Campbell's Cream of Mushroom soup, green beans, milk, soy sauce, pepper, and French's French Fried Onions. Her recipe was featured in a 1955 Associated Press feature about Thanksgiving, and the association has proven surprisingly durable—Campbell’s now estimates that 30 percent of their Cream of Mushroom soup is bought specifically for use in a green bean casserole.

9. Pumpkin Pie

Like cranberries, pumpkin pie does have ties to the original Thanksgiving, albeit in a much different format. The colonists certainly knew how to make pie pastry, but couldn't have replicated it without wheat flour, and might have been a bit perplexed by pumpkins, which were bigger than the gourds they knew in Europe. According to Eating in America: A History, however, Native Americans were already using the orange treats as a dessert meal: "Both squash and pumpkin were baked, usually by being placed whole in the ashes or embers of a dying fire and they were moistened afterwards with some form of animal fat, or maple syrup, or honey." It's likely that Hale was inspired by those stories when pumpkin pie appeared in her culinary descriptions.

10. Wine

Chances are good that a few glasses of wine will be clinked around your table this November, but did the pilgrims share a tipsy toast with their new friends? Kathleen Wall thinks that water was probably the beverage of choice, considering that the small amount of wine the settlers had brought with them was likely long gone. Beer was a possibility, but since barley hadn't been cultivated yet, the pilgrims had to make do with a concoction that included pumpkins and parsnips. Considering the availability of apples in what would become Massachusetts, however, other historians think it's possible that hard apple cider was on hand for the revelers to enjoy. Whether or not the original feast was a boozy affair, cider rapidly became the drink of choice for English settlers in the area, along with applejack, apple brandy, and other fruit-based spirits. New England cider thus indirectly led to a less-beloved Thanksgiving tradition: your drunk uncle's annual political rant. Bottoms up!

8 Festive Facts About Hallmark Channel Christmas Movies

The holiday season means gifts, lavish meals, stocking stuffers, and what appear to be literally hundreds of holiday-themed movies running in perpetuity on the Hallmark Channel, which has come to replace footage of a crackling fireplace as the background noise of choice for cozy evenings indoors. Last year, roughly 70 million people watched Hallmark's holiday scheduling block. If you’re curious how the network manages to assemble films like Check Inn to Christmas, Christmas at Graceland: Home for the Holidays, and Sense, Sensibility & Snowmen with such efficiency—a total of 40 new films will debut this season on the Hallmark Channel, Hallmark Movies and Mysteries, and Hallmark Movies Now—keep reading.

1. The Hallmark Channel Christmas movie tradition started with ABC.

The idea of unspooling a continuous run of holiday films started in the 1990s, when ABC offshoot network ABC Family started a "25 Days of Christmas" programming promotion that would go on to feature the likes of Joey Lawrence and Mario Lopez. The Hallmark Channel, which launched in 2001, didn’t fully embrace the concept until 2011, when ABC Family moved away from the concept in an effort to appeal to teen viewers.

2. Most Hallmark Channel Christmas movies are shot in Canada.

To maximize their $2 million budget, most Hallmark Channel holiday features are shot in Canada, where tax breaks can stretch the dollar. Wintry Vancouver is a popular destination, though films have also been shot in Montreal and Toronto. One film, 2018's Christmas at the Palace, was shot in Romania to take advantage of the country's castles.

3. Each Hallmark Channel Christmas movie only takes a couple of weeks to film.

If you’re wondering why a holiday movie on basic cable can regularly attract—and keep—a list of talent ranging from Candace Cameron Bure to Lacey Chabert, the answer is partly scheduling. Most Hallmark holiday movies take just two to three weeks to shoot, meaning actors don’t have to commit months out of the year to a project. Actors like Rachael Leigh Cook, who stars in this year's A Blue Ridge Mountain Christmas, have also complimented the channel on giving them opportunities to be with their families while on location: Cook said that the production schedule allowed her time to FaceTime with family back home.

4. Hallmark Channel Christmas movies use a variety of tricks to create snow.

Even more pervasive than Dean Cain in the Hallmark Channel Christmas line-up is snow. Because some of the films shoot in the summer, it’s not always possible to achieve that powder naturally. Producers use a variety of tricks to simulate snowfall, including snow blankets that mimic the real thing when laid out; foam; commercial replica snow; crushed limestone; and ice shavings. Actors might also get covered with soapy bubbles for close-ups. The typical budget for snow per movie is around $50,000.

5. There’s a psychological reason why Hallmark Channel Christmas movies are so addictive.

Like a drug, Hallmark Channel Christmas movies provide a neurological reward. Speaking with CNBC in 2019, Pamela Rutledge, behavioral scientist, director of the Media Psychology Research Center, and a faculty member in the Media Psychology department at Fielding Graduate University, explained that the formulaic plots and predictability of the films is rewarding, especially when viewers are trying to unwind from the stress of the holiday season. “The lack of reality at all levels, from plot to production, signals that the movies are meant to be escapism entertainment,” Rutledge said. “The genre is well-defined, and our expectations follow. This enables us to suspend disbelief.”

6. Hallmark Channel Christmas movie fans now have their own convention.

Call it the Comic-Con of holiday cheer. This year, fans of Hallmark Channel’s Christmas programming got to attend ChristmasCon, a celebration of all things Hallmark in Edison, New Jersey. Throngs of people gathered to attend panels with movie actors and writers, scoop up merchandise, and vie for prizes during an ugly sweater competition. The first wave of $50 admission tickets sold out instantly. Hallmark Channel USA was the official sponsor.

7. Hallmark Channel Christmas movies are helping keep cable afloat.

In an era of cord-cutting and streaming apps, more and more people are turning away from cable television, preferring to queue up programming when they want it. But viewers of Hallmark Channel’s holiday offerings often tune in as the movie is airing. In 2016, 4 million viewers watched the line-up “live.” One reason might be the communal nature of the films. People tend to watch holiday-oriented programming in groups, tuning in as they air. The result? For the fourth quarter of 2018, the Hallmark Channel was the most-watched cable network among women 18 to 49 and 25 to 54, even outpacing broadcast network programming on Saturday nights.

8. You can get paid to watch Hallmark Channel Christmas movies.

If you think you have the constitution to make it through 24 Hallmark Channel holiday films in 12 days, you might want to consider applying for the Hallmark Movie Dream Job contest, which is sponsored by Internet Service Partners and will pay $1000 to the winning entrant who seems most capable of binging the two dozen films and making wry comments about them on social media. You can enter though December 6 here.
