MS Gulf Coast is home to only photographed living giant squid

Giant squids are the things nightmares and science fiction movies are made of. Squids are not the most adorable things to look at unless you're a zoologist or marine biologist. These ocean-dwelling creatures look like they would eat you if given the chance though, thankfully, this is not a worry most people need to have. Unless you are going deep into the ocean far removed from the United States, your chances of running into a giant squid are quite low.

But they aren't zero. It turns out you don't have to go to some far off country to see a giant squid in the wild;, you just have to go to Mississippi. Marine mammal researcher for Mississippi State University’s Coastal Research and Extension Center, Dr. Holley Muraco reveals in an interview with the Mississippi Department of Wildlife, Fisheries and Parks that the waters right off of the Mississippi Gulf Coast are home to the only living squid photographed in North America.

The Mississippi Gulf Coast water is home to a lot of different aquatic critters. It's a place known for it's sea food and home to the Institute for Marine Mammal Studies, a nonprofit organization that rescues and rehabilitates injured marine animals and houses those who can't be re-released into the wild. The organization also serves as a center for education on the different types of marine animals with interactive live animal shows at a fraction of the cost of visiting an aquarium. Mississippians are used to sharing the water with the different fish that live in the bay, bayou, sound, Gulf, and the ocean waters beyond the Gulf.

A lot of time in Mississippi is spent outside on or near a body of water whether it's fishing off of a pier or kayaking in the bay. Gulf Coast residents have learned to peacefully exist with the animals that come with the territory, including alligators. But the discovery of a living giant squid in the body of water Mississippians enjoy year round is a surprise to locals and their Gulf Coast neighbors in the neighboring states.

"Are you serious? If Mississippi residents actually knew this, they would be ecstatic to share it. I was born and raised in MS and that's the first I've ever heard it. I actually witnessed a manatee in Biloxi Bay as a kid and no one believed me," one person exclaims on a short clip of the interview.

"As an Alabama resident, knowing they found giant squid off the coast of Mississippi doesn't make me feel more comfortable with being offshore," someone else shares.

Giant squids aren't something people imagine much outside of movies or "scholarly" debates after a few drinks on who would win in a fight, a giant squid or a sperm whale. Turns out the sperm whale versus squid match is due to researchers once finding pieces of a large squid inside the belly of s sperm whale. Mississippians can rest assured that their waters would be the scene of the next rematch if there ever was one because according to Dr. Muraco, they've also spotted the huge sperm whales in the same water.

"We have a resident population of sperm whales, right off, maybe 60 miles off of Gulfport. A resident population of sperm whales and so we know that we're having sperm whales with epic battles of giant squid. That's happening in our backyard, ya know. I'm like, it's crazy." Muraco excitedly tells the host before adding, "And I just want anybody who will listen to know, we can take ownership of this. Mississippi has the best access to that Mississippi Delta, Desoto Canyon, that magic place right there where all these marine mammals are trying trying to survive."

Dr. Muraco also exclaims that Mississippi is also the home of Rice's whales, the most endangered species of whales in the world. According to the National Oceanic and Atmospheric Administration (NOAA), there are fewer than 100 Rice's whales in the entire world. The Gulf really does have diverse marine life.

People in Mississippi are no strangers to the giant squid—they're just not accustomed to them being alive. The first giant squid seen in the Mississippi coastal waters was found floating in 1954, and the second was pulled from the water in 2009 as researchers were looking for prey of sperm whales in the area. The squid caught in 2009 was 19.5 feet long and weight 103 pounds.

“This is an incredibly rare find in the Gulf of Mexico,” said Michael Vecchione, director for NOAA’s Fisheries Service’s National Systemics Laboratory. A giant squid expert told the Smithsonian Insider the same, highlighting the gravity of the occurrence “Giant squid have been found more commonly in areas of the world where there are deep-water fisheries, such as Spain and New Zealand, but this is the first time one has actually been captured during scientific research in the Gulf of Mexico.”

A more recent expedition in 2019 with a specialized underwater camera named "The Medusa" caught a glimpse of a living juvenile giant squid estimated to be between 10 and 12 feet long. A video shows the squid coming to eat the e-jelly lure placed on the camera before swimming away after realizing it wasn't actually food.

Being that the squid is a juvenile, it's likely that there are more squids in the depths of the Gulf. It's just a matter of time before researchers capture evidence of older squids.

Amazing ocean facts you never learned in school

Not even Captain Ahab knew this much about marine life.

The ocean covers more than 70 percent of our planet—yet there’s so much about it that we don’t yet know. Experts, in fact, believe we’ve only explored about five percent of the ocean so far—meaning that most of it remains completely unseen and undiscovered.

What we do know, however, is that the ocean is truly wise. Not only does it sustain all human and animal life on the planet, the creatures under the sea continue to give scientists insight that can transform human lives as well (just read about the amazing axolotl below to see what we mean).

A happy ocean makes for happy, healthy human beings (not to mention a healthy planet)—so this summer we’re helping our friends at Ocean Wise spread the word that no action is too small—holding a cleanup on a local shoreline, for instance. Learning about our ocean and all its wonders is another step anyone can take for conservation, so buckle in and prepare for a tidal wave of info that will blow your mind.

1. Playing music—specifically, recordings of healthy reef soundscapes—can help grow coral reef populations.

Healthy coral reef populations are filled with diverse sounds, thanks to the fish, snapping shrimp, and other marine life that live there. Scientists have found that playing recorded sounds of healthy reefs actually attract coral larvae, since the sounds indicate a healthy, vibrant habitat. Using this knowledge, scientists have taken recorded reef sounds, played them near degraded reefs, and in doing so, have increased the settlement rates of coral larvae, helping the coral reefs regenerate.

2. Dolphins like to party with pufferfish.

How’s this for a good time? Dolphins, particularly younger ones, have been known to seek out pufferfish to play games with them, chewing on them and passing them back and forth between each other like a hacky sack. Not only is this entertainment for the dolphins, scientists theorize that they may intentionally be trying to get the pufferfish to give off a neurotoxin called tetrodotoxin (TTX)–which is a chemical they release when threatened. This chemical is highly toxic in large doses–but in small quantities, experts think that it might induce a mild, pleasurable effect in the dolphins, similar to a narcotic. Party on.

3. Male humpback whales are total crooners.

All humpback whales can vocalize, but male humpback whales actually sing.

During mating season, scientists have observed male humpback whales making sounds that are distinctly different from other humpback calls. Unlike other sounds, these songs have a clear structure, and use small, repetitive “phrases” organized in a specific sequence—in the same way humans sing different verses during a song. Even more amazing? Male humpbacks all sing the same song together in “choruses,” in sessions that last from five minutes to several hours.

4. Axolotls have superpowers (and scientists think it could benefit humans one day).

Among biologists, axolotls are known for their ability to regrow lost or damaged tissue. When an adult axolotl loses a limb, they can actually grow it back in just a few months time, thanks to a substance they produce called retinoic acid, which plays a large role in regenerating skin cells. (If the name sounds familiar, it’s because retinoic acid is a derivative of Vitamin A, and it’s commonly found in skin creams.) While we already know that retinoic can make our skin look fabulous, scientists are currently studying whether it could someday help human limbs regrow, similar to the axolotl’s.

5. A healthy ocean can help reverse climate change

The ocean generates half of the oxygen we breathe and absorbs nearly a third of the world’s carbon emissions. Phytoplankton, the microscopic algae that float near the ocean’s surface, are a big part of the reason why. But there’s another unsung hero—kelp. Unlike phytoplankton, kelp are large seaweeds that grow in dense underwater forests along coastlines, absorbing CO2 and supporting ecosystems. Ocean Wise is helping bring back these powerful carbon sinks one kelp forest at a time.

Help us #BeOceanWise by doing one small thing for ocean conservation in your community (because just one thing can start a huge wave of positive change). Visit ocean.org for tips and tricks to keep our oceans healthy because no action is too small.

A scientist created a 'utopia' for mice and then they all started dying

The results are fascinating, but are they relevant to humanity?

How could Mouse Heaven go so terribly wrong?

In 1968 John Calhoun, a scientist and animal behavioralist, decided to create a "utopia" for mice. It would have unlimited food and water, with beautiful nesting spaces and plenty of materials for the mice to make cozy homes with. Sweet experiment! the mice were probably thinking. Much better than the Maybelline trials we're used to.

However, there was a catch, of course. There was one thing the utopia would be lacking, and that would be physical space. As the mouse population grew, overcrowding would become an issue, and Calhoun wanted to study the problems this would potentially cause. That sound you hear is the collective sigh of the disappointed mice who were stoked about the 24/7 all-you-can-eat buffet.

The experiment, dubbed Universe 25, began when Calhoun introduced four mouse "couples" into the utopian complex. A year or so later, it was overrun and the conditions had turned hellish, even though the mice had not run out of food or water.

Initially, for just the eight original mice, the square box Calhoun built included 256 nesting boxes (or apartments) stacked on top of one another. Water bottles and food dispensers were located all along the nesting spots, and mice could travel throughout the complex at will via mesh tunnels. The starter mice were also screened for diseases and the population was obviously protected from predators. The climate was controlled and comfortable. Conditions were perfect.

The first mouse pups showed up a little over three months later, with the population of the colony doubling every 55 days. Nineteen months later, there were 2200 mice living inside the box. With such perfect surroundings, the infant mortality rate was practically zero, leading to the rapid rise in numbers.

By month 19, this rodent utopia had become an overcrowded hellscape. Calhoun noticed three alarming trends, in particular.

In short, everything was devolving into chaos and the very society of the mice began to collapse at a rapid rate.

The "Beautiful Ones" and the "Dropouts": Mice have a complex social hierarchy ruled by dominant alpha males. Sam Kean of Science History Institute Museum & Library notes that, in the wild, non-dominant males (the ones who lose macho showdowns) can skip town and start over somewhere else. But in the close quarters of Calhoun's experiment, with nowhere to hide, they were forced to hang around and viciously battle with each other over scraps. Eventually, non-dominant male mice, which Calhoun called the "Beautiful Ones," withdrew from society completely and only ate, slept, and groomed themselves.

Though resources were unlimited, certain aggressive males hoarded them anyway: The alpha males ruled over everything in the once-utopian mouse society. They kept harems of females in the apartments to mate with and fought fiercely to defend their territory. But new waves of hungry young male mice kept coming and coming, and eventually even the most dominant alphas abandoned their posts. This led to more attacks on nursing females, which in turn led to more mothers kicking their pups out of the nest early.

Birth rate declined dramatically: With the non-dominant males giving up completely and focusing on #SelfCare, dominant males too exhausted from endless battles, and females sick and tired of it all (many became asexual hermits by the end), stopped mating and giving birth entirely. Once this happened, the society was doomed. Even with plenty of food still available, cannibalism was rampant.

Calhoun was not shy about drawing parallels between his research and humanity. "I shall largely speak of mice, but my thoughts are on man, on healing, on life and its evolution," he once wrote.

There are aspects of his wild experiment that certainly sound familiar.

We live in a world with plenty of resources for everyone, but a few select people hoard more than their fair share. When you think of the rodent "apartments," it's hard not to picture densely packed urban environments where people are stacked on top of each other at every turn. Maybe on some level some of us can relate to the “Beautiful Ones” and their urge to not participate in all the ugliness and just sequester and groom themselves. You can make an argument that when the mice stopped having to worry about food and shelter, it removed the element of challenge from their lives and left them lost–like many of us are lucky enough to not have to wonder where our next meal comes from, and maybe that has something to do with our never-ending search for meaning. Some even go so far as to link more people choosing to delay having children, or not have children at all, with the collapsing society of the mice.

But Calhoun's work has also been heavily scrutinized, with some claiming it's based on shaky science. And in the end, there’s the small matter that humans are not mice. We are infinitely more complicated, and so much better suited to adapting to our environments. Kean writes, "Ultimately Calhoun’s work functions like a Rorschach blot—people see what they want to see."

It's fascinating and thought-provoking nonetheless.

Forget what you know about bed bugs. Avoiding and getting rid of them is pretty simple.

And thankfully, there are no toxic chemicals involved.

Mark Rober/YouTube

Mark Rober subjected himself to bed bug bites in the name of science.

"Good night! Sleep tight! Don't let the bed bugs bite!" This sing-songy rhyme that has been around for centuries alludes to the fact that bed bugs were prevalent in the past. After a significant decrease post-WWII, however, the sneaky pests have been making a comeback. Since the 1990s, bed bug infestations have risen dramatically, leading people to look for ways to avoid and get rid of the blood-sucking little buggers.

Unfortunately, a lot of the information about how to do that is flat-out wrong. Popular YouTube science communicator Mark Rober invites viewers to forget what we think we know and go on an educational journey with the leading bed bug researchers at Rutgers University's urban entomology lab. Not only did Rober subject himself to bed bug bites on purpose to see what happens when they feed, but he also conducted a series of experiments in the lab to find out what is actually effective at killing them and what is not.

Bed bugs have a reputation for being nearly impossible to get rid of, which isn't really the case, according to Rober. When you know what works, it's actually a fairly simple process to kill an infestation. And the good news is that it doesn't entail any toxic chemicals—in fact the pest control chemicals sold for bed bugs don't work at all, according to Rober's tests.

In the process of learning about bed bugs, Rober shared a few "super wild" facts about the infamous creatures.

Fact #1: Bed bugs can live 3 to 10 months without feeding.

Eek. No wonder it seems like it's impossible to get rid of them. Starving them doesn't work. They can live in the resting stage for 3 to 6 months, and if the environment is cold enough, they can survive around 300 days, or 10 months, without eating.

Fact #2: Bed bugs don't transmit disease

Some good news here: Unlike blood-sucking mosquitoes, bed bugs don't carry or transmit disease. The bad news on the front is that because they don't pose a disease threat, only an annoyance, there's not a big incentive to fund research to eradicate them.

Fact #3: Bed bugs are attracted to vertical objects

In one of Rober's experiments, he placed a dish with a cylindrical vertical post inside it an a dish without a column, and nearly all of the bed bugs in the enclosure ended up in the dish with the column. "If you think about it, humans sleep at the highest elevation any given room. So their logic is just crawl up any vertical surface you see until you eventually find a warm-blooded meal at the top."

Part of how they find humans is by smell, which is why certain strong-smelling items can act as a deterrent for bed bugs. In Rober's experiment, Bounce dryer sheets, moth balls, baking soda, and essential oils all seemed to repel bed bugs (as opposed to ultrasonic pest repellers, which appeared to have no effect). However, none of those things did anything to kill them.

Fact #4: Before 1950, one in three homes had bed bugs

Yikes. Even with the resurgence, we're still nowhere near those numbers, thank goodness.

Fact #5: The way bed bugs mate is weird

The term used to describe it is called "traumatic insemination," and really, you should just let Mark Rober explain it with his visual metaphor. Start at minute 11:30.

Two things work well to kill bed bugs—diatomaceous earth and heat

In testing chemical sprays, foggers, and other items marketed for killing bed bugs, Rober found a "superstar" in a natural, non-toxic substance. Diatomaceous earth—pulverized fossilized remains of tiny aquatic organisms called diatoms—was the most effective at killing the buggers with a 90% mortality rate after 10 days as opposed to 12% with the Hot Shot bed bug spray. Diatomaceous earth is mostly silica, which absorbs moisture, and when the silica dust sticks to the bed bugs as the walk through it, it dehydrates them. A light dusting of diatomaceous earth around all the cracks and crevices of a room is one way to kill off an infestation, though that process can take days.

The other way to kill bed bugs is heat. Steam kills bed bugs, as does heating up a room to over 122 degrees Fahrenheit does the trick. Temps over 122 degrees kills bed bugs instantly, and as Rober points out, there's no way for them to build immunity to this kind of treatment. So steamers and clothes dryers set to high are the average person's best bet for killing off bed bugs if they have them. The "nuclear option" is to have a pro come in with big heaters and cook your home for a day.

How do you avoid getting bed bugs in the first place?

An ounce of prevention is worth a pound of cure, and that's true for bed bugs especially. Avoiding an infestation if there's already one in your apartment building is trickier, but a lot of people inadvertently bring bed bugs home from hotel stays. Checking the underside of a hotel mattress as soon as you come in the room is a good habit to be in. Bed bugs poop a lot, and there will be spots along the edges of the mattress if bed bugs are present.

The other tip is to use the luggage rack to store your suitcase instead of leaving it on the floor or furniture and to hang clothes on the closet hangers instead of putting them into the hotel room's dresser drawers. Some people may even put their suitcase in the bathtub, at least until they've checked the bed for signs of poop.

Nobody wants to deal with bed bugs, but at least now we have clear evidence of what actually works to get rid of them and what doesn't. Cook them with heat/steam and dehydrate them with diatomaceous earth, and take some simple steps when traveling to lessen your chances of getting them in the first place.

Sleep tight, everyone!
