New York State has announced they are proposing to “shut off” Niagara Falls sometime in the next few years. You may be reacting like us. First of all, HOW do you shut off an insane amount of water flowing over a cliff, and secondly, WHY??
We’ll start by saying diverting all this water is surprisingly possible. It was done once before in 1969, to study the effects of erosion and basically to see what was underneath all that water. It was done with a cofferdam, a engineering marvel that creates a watertight enclosure around a certain area of the water to divert the flow, and in some cases pump the inside dry. The plan is the same as in 1969, to use a cofferdam to divert the water from American Falls over to the larger Horseshoe falls leaving the American Falls to go dry, or be dewatered.
Let’s just take a second and think of the size of this project. It’s estimated that 75,750 gallons of water flow over the American and Bridal Veil Falls per second. PER SECOND. We think that qualifies as an interesting engineering marvel.
As for the why part of the proposal to dewater the falls? This time the project is for safety reasons. New York State wants to repair the two stone-faced concrete arch bridges built in 1900, that give access to Goat Island. There were temporary repairs in 2004, but the main structure continues to erode.
There are people that remember when the falls last went dry in 1969. The Buffalo Newsrecounts the stories of what was found when the water dried up and the curiosity the falls became with NO water.
Right now the plan is only at the proposal stage, and hearings will be held about the process and plans for the bridges. There are many that oppose the plan to dewater the falls for the second time in less than 50 years. Could the cofferdam damage it’s surroundings? Would the sun on the rocks change them irreparably? Not to mention, the various opinions on the design of the bridge repairs.
We’ll be watching to see what is decided. We love nature, but we also love an epic engineering project, so we’re on the sidelines on this one. Watch some video below from the first dewatering in 1969, find out how a coffer dam is made, and get the full story via The Buffalo News.

In a paper just published in The Astronomical Journaltoday, two CalTech scientists report compelling circumstantial evidence for the existence of “Planet X.” The mysterious ninth planet. Dr. Michael E. Brown and Dr. Konstantin Batygin base their evidence on extensive computer modeling focusing on the far reaches of the solar system, beyond Pluto.
The tip off comes in the form of six objects observed to be in some kind of orbital cluster. While they have wildly varying elliptical orbits, they all loop and tilt in the same direction. This kind of orbital tracking has been the tip of for the existence of other planets before. In fact, the orbit of Netpune predicted the existence of Uranus. Scientists put the odds of this type of orbital cluster happening naturally at a 1 in 14,000 to 15,000.
It is believed this ninth planet would be somewhere near the size of Neptune and somewhere around 10 times the mass of our Earth. That would dwarf poor Pluto.
The mindblowing aspect of Planet X is its distance. It would be somewhere around 20 billion miles from the sun at its closest, and in its farthest point it would be 100 billion miles. To give you context, Pluto is closest to the sun at 4.6 billion miles. With these kind of numbers it is estimated it would take an astounding 10,000 to 20,000 years to complete just ONE orbit around the sun.
Keep in mind this evidence is circumstantial, but strong. The scientists haven’t actually SEEN the ninth planet yet, but Brown and Batygin believe it could be spotted by telescope in the next five years.
No matter what happens in the next five years, we’ll still always hold a place in our hearts for Pluto. Explore these videos which explain the orbital cluster and show an animation of "Planet X."
Editor's Note: Les has very kindly put together a blog on basics on what should go into a survival kit. It couldn't be more timely as we get ready for the season finale tomorrow night @ 10p in Patagonia. We'll be giving away three of Les' Survival Kits for those who use the hashtag #SurvivormanKitSweeps - but only during his show tomorrow night! We have other content popping up as well so key an eye out on social media. We can't wait to talk to you there and hope you enjoy the finale. Now on to Les' tips:
It is so very tempting, when faced with the concept of surviving in the wilderness, to want to carry with you the ultimate survival item. Is it a lighter? A knife? Food? No…..ok it must be water? Nope wrong again. Actual victims of survival have been asked time and again what they felt was the number one thing you need to survive in the wilderness. The answer: (and you can’t buy it at the outdoor store) the will to live.
There are documented cases of lost victims found dead beside a backpack of supplies. They lost their will to live. There are also fantastic stories of people suffering horrendous ordeals with nothing and they survived. Their will to live was strong.
But ok let’s get beyond the psychology of it all. I still just want to head out camping and carry with me a few items that, just in case I need them, will better my chances for survival. But now it all depends doesn’t it? Are you going to Africa? Costa Rica? The Arctic? Northern Ontario? And what time of year is it?
Suffice it to say – there is no one item that will ensure you make it back with great photos, all your limbs and the movie rights to your story up for grabs.
So I can only relate this personally now: If you are sending me off on a winter trek in Canada and you are giving me three choices, I will likely take a sharp axe, a water proof butane lighter and assuming I am dressed properly, a small pot to boil water in.
So you see, assuming I’m not injured, I have a way to split wood, make a huge fire and boil up some spruce tea. In the summer I will trade in the axe for a good tarp. This is the minimalist approach however. The ideal is as follows:
Firstly let’s get these items in your pockets…you can’t leave your pockets at the last camp site. If you really must, a fanny pack can carry the larger items but remember: if it is too big and heavy you will just not want to carry it around with you. Oh and couples – one other thing – DO NOT have a joint survival kit – keep It personal – if they’ve got the kit and you lose them – you lose the kit.
(Leaving out first aid for the time being) - Here’s my minimum kit - FOR SURVIVAL ONLY – (keep separate from your camping supplies):
In pockets or hanging from your belt;
· High quality (sharp) knife · Compass · Solid matches with striker in a waterproof container · Butane lighter · Magnesium flint striker (hey – I like fires!) · One or two large ORANGE garbage bags · Metal cup (for boiling) · Rope (Parachute cord is great) · Whistle
In a small kit or fanny pack (try a coffee tin with a lid – you can use it for boiling);
· Dried foods · Insect screen (seasonal) · Signal mirror · Small flashlight with batteries · Snare wire · Fishing lures (3), hooks, sinkers and line · Some two inch nails · Candle · Flares
You must!!!! – Know how to use everything in your kit!
BUT!!!!; No single item is as important as some real survival training….kits can be lost and give a false sense of security. Survival should depend on your ability to adapt…your will to live….not on a single item you left back on the portage trail. ~ Les Stroud
EDITOR'S NOTE: We were thrilled to just receive this update from Les Stroud giving us the inside story on his latest activities, written specifically for this blog and you, his fans. We've wouldn't dream of editing Les' words - after all, he's the story teller! Enjoy!!
As the latest batch of Survivorman episodes rolls out on the TV screens you would think I would take the time to chill out a little bit and relax before getting into something all consuming again. And I really should. But alas, that is not my usual way. I absolutely loved the variance of Survivorman expeditions this year from the Search and Rescue episodes shot in Transylvania, to the teaming up with two fine women for the Conne Family expose in Oregon, to the inclusion of a fan this year based on a contest.
I await news on whether or not I will be asked to head back out for more filming and you will all know as soon as I do. In the meantime I suppose I am getting a little bit of down time fishing in Oregon on the Rogue river for Steelhead and getting out with my son and daughter for some hiking. But career wise I am focused on the development of Survivorman’s Mother Earth tour. A live stage production where I have big screens highlighting some of my video work from around the world – a full 6 piece rock band performing my music to the images on the screens and including some chilled, intimate moments of Q&A with the audience where I answer questions on everything from Survivorman and Bigfoot to how we can all connect to the earth in more meaningful ways as human beings.
Over the years of producing Survivorman (its been almost 15 now!!) I have often referred to various mentors that I have looked to, to do my work as a film maker and to pass on good and worthwhile instruction. Teachers like Mors Konchanski, Larry Dean Olson, Dave Halladay, Bradford Angiers, Dave Westcott and John and Geri McCpherson have all been heroes and teachers for me either through direct contact or their published works. It is from these esteemed instructors that I first learned the craft, art and skill of wilderness survival. And that was always the first original (and remains to this day) goal of the Survivorman series; to teach survival skills. No stunts. No tricks. Just pure survival for what it is – when it is good and when it is bad. Warts and all as we say.
Along the way a second subtext of teaching became apparent to me. Well perhaps not so much teaching as inspiring. And that was to simply re-connect with nature. This doesn't take going to Peru or Africa – there is beautiful nature usually just down at the end of your street. The local parks have nature you can touch and smell and experience and in doing so you absolutely reconnect. I used to do this underneath a freeway overpass close to Toronto, Ontario by a creek. Noisy? Yes. A little polluted? Yes, but it was still a natural spot in a busy city and it gave me respite. That continues to be the message of Survivorman as well; to connect with nature. There we other mentors throughout the making of Survivorman I owe a great deal of gratitude to; film makers. I often would try to emulate great filmmakers in my work on Survivorman. This was a big part of my passion in being out there; to film a great story and show it beautifully. I think likely my number one influence was a Canadian Oscar award winning filmmaker named Bill Mason. I probably still set up certain moments on film in ways that I noticed him doing years ago.
Lets see where things go from here. Another book? Maybe. I was interested in doing a field guide to finding Bigfoot but I cant get a publisher interested. I have two new CD’s in the works; one is more of a roots acoustic thing and the other is an epic art rock album including, so far, solos from Slash and Steve Vai. And lastly more Survivorman? Well that's not up to me – its up to the ratings and the networks who have always been good to me over the years so I stand at the ready to do what I always do; try to remain a prolifically creative and involved artist/film maker/adventurer. I’m still working on it!
We’ve all the heart pounding moment. Maybe it is from a cloud formation or water spout in the ocean you’ve never seen before, hearing an astronaut tell a story of near death, seeing your child be born, or perhaps it’s show on how the universe came into being. It’s that mind-blowing, “wow” moment where you are awe-struck.
You may not think of it this way, but awe is actually an emotion. Many in science and psychology didn’t think much about it until studies were done about 10 Years ago to find out what it really meant to be awestruck and whether it was important to us as a part of our other range of emotions.
What exactly IS awe? According to researchers, awe is having a feeling you’ve seen, heard, or met someone or something much larger than your everyday experience. It stops you and makes you think. With it goes seems to go the sense of needing to pay it forward and tell someone about it. To spread the knowledge or vision gained.
This insight comes from psychologists Dacher Keltner and Jonathan Haidt decided to try and decipher the science of awe in 2003. After asking people to make a face describing awe, it was eyes wide open and mouth dropped. It seems awe is not funny or smile producing. It’s something serious and can be triggered by seeing something positive or negative, but the one result is this emotion makes you think when you experience it and want to discuss it with others in an attempt to understand or rationalize what you’ve experienced.
Other researchers noted it’s also not necessarily a “comfortable” emotion because you are processing and thinking about something you’ve never seen or heard before and you don’t necessarily know the the outcome. Is awe the recognition of the unknown?
Another researcher, Melanie Rudd, assistant professor of the University of Houston found people described it as “timeless.” When experiencing awe time seems to stand still or not exist at all reported study subjects.<< cont. below>>
So we know awe is an emotion tied to thought, understanding and needing to understand and share something we don’t understand. A wow moment can be beautiful or terrifying, like seeing an eclipse for the first time, or a tornado starting to form. What purpose could being stopped in our tracks possibly serve?
The researchers studying awe came up with two evolutionary explanations. If you are awe-struck you may pause to think about danger, cause, and the best possible reaction. From an evolutionary level being awed and cautious may have saved us from life or death situations, allowing humankind to survive and evolve, gathering knowledge along the way.
The other explanation is the need to explain the awe inspiring experience and to involve others. In other words, at a basic level it is a way of pulling a group together to understand a phenomenon. It could be defensive and for self preservation as spreading the word about a giant tornado formation might be. Or, it could be the twinge of curiosity about something and the desire to gain knowledge for others – such as studying the movement of the heavens to define time.
Whether awe causes us to be cautious or curious, the primal outcome is the same. Being awe-struck helps us come together and continue to evolve as a species.
If the basic outcome of awe is coming together, researchers such as Rudd and Keltner continue to study how this shapes our every day behavior. It is linked to every day curiosity, listening to each other and a sense of humility, open-mindedness, and connection.
Awe is something we can see hard enough if we look everyday as well. It doesn’t have to be the large, Earth changing event. It could be visiting a new country, or learning about how something complex is made – we certainly see that in Mike North’s face as he visits the LG TV factory in Korea and gets a lesson in the new OLED technology. His curiosity for “How does this work??” is paid forward to us as he dives into questioning the LG Team.
We get “wow, so that’s how it works!” moments of learning why an OLED TV can deliver a “true black.” This new category of televisions use LEDs in them to create the true definition by being able to turning off the light in the pixels that don’t need them. It’s the absence of light, not a dimming or projection of black that makes the difference.
Seeing how thin and flexible they are is also amazing. Doc North can actually bend the screen with his hands! To think we’ve come from giant consoles using cathode tubes, to wafer-thin, see-through screens is a pretty awe-inspiring example in the evolution of technology.
LG OLED TVs have been called “perfect” for gamers and movie buffs. Why? It gets back to the awe thing. By being able to play a game that renders the virtual world with such realism and by showing movies with the beautiful, colorful pictures the directors could see in their mind is incredible. You want to play with your buddies and you want to gather your friends to enjoy a brilliant movie so you can all leave with open mouths at whatever your experience of choice was. Far from isolating us like some would claim about new technology, this one actually brings people together.
What does all this prove? That awe is an emotion that can be generated by many things. It depends on the person whether it’s a rainbow or experiencing the vastness of a modern factory. What remains the same is that we all have that twinge that stops us in our tracks, that makes us think, and perhaps build on what has excited us.
It is awe that may spur us to inhabit the Moon or Mars, and combined with curiosity it is an emotion researchers are proving should be respected and nurtured.
Did you know that, yesterday August 20th was National Lemonade Day? Lemonade is probably the most popular thing we think of when it comes to lemons. There are fewer things nicer on a hot summer day than an ice-cold glass of inexplicably sweet-tart lemonade.
There’s much more to lemons than just lemonade however, and just because summer comes to an end doesn’t mean we should stop loving and celebrating them. Lemons are gifted with some pretty powerful natural substances that make them not only smell and taste good, but can do some amazing things for your body, inside and out.
Let’s get to know the four key ingredients in lemon juice and then break down just ten of the many things they can do. Lemon juice contains:
Citric acid – Citric acid is a weak organic acid that acts as a preservative and a part of the metabolic process in aerobic organisms. In addition to being a preservative, it also adds taste to certain foods.
Limonene – Limonene is a colorless, liquid hydrocarbon with a strong smell, found concentrated in the rinds of citrus. In various molecular forms, it can be used in everything from solvents to medical applications, including new research on battling cancer cells.
Ascorbic Acid – Ascorbic acid is a naturally occurring compound that has anti-oxidant properties. It is also known as Vitamin C, which has countless health benefits.
Lemon Oil – Lemon oil is a naturally occurring oil found in the rind of the lemon; unlike many other oils it is generally not distilled from the fruit but cold-pressed. In addition to being valued for its strong smell, it is also said to have antibiotic properties.
Together the ingredients in lemon juice have a very low pH number, meaning they are acidic – which is no surprise to anyone. Some people love the sour tang of lemons, but beyond taste, the acid in lemon juice can have an effect on the body, even at a cellular level.
So should we see lemons as a magic food waiting in the wings to be consumed en masse? It’s true that lemons and lemon juice is the subject of ongoing cancer research, including some interesting new tests involving other compounds they’ve been found to carry. To add perspective, remember lemons are relatively small and provide a small amount of juice. You’d have to eat a lot of lemons for their juice to have a clinical impact.
Lemons CAN be a great addition to your daily diet and routine. They help aid with some common health problems, and research may prove eating them regularly may even prove to have some important preventative effects.
We love them not only for the health problems they can address, but they are a great to add to your arsenal of sustainable living practices. How? Once you’re done with the juice or the zest, you can cut the lemon into wedges and use them to deodorize and clean everything from your garbage disposal and trash cans to making your fridge smell nice and help scrub your pots and pans. Nothing goes to waste!
So let’s get to it and geek out on just some of the ways the lemon shows us some love.
Acne – While most of our body has a naturally regulated neutral pH balance, it turns out our skin really likes the acid in lemons. Bacteria living on our skin and in our pores often cause nasty breakouts, inflammation and acne. For some, the addition of lemon juice on a cotton swab makes the skin a less of a breeding ground for overactive bacteria on the skin’s surface. Scientists in Korea have found that lemon juice not only curbs the bacteria, but also acts on chemical messengers within that triggers our immune systems to overreact to the bacteria by creating redness and even killing skin cells.
Anti-Aging – All that vitamin C in lemons can help to battle free radicals – highly unstable, quick moving molecules formed from weak chemical bonds that break apart. That creates some hungry molecules looking to repair their own bonds and when our skin cells are in their path they work to steal molecules from our tissue, breaking down cells in the process. Aging. While some of this happens naturally during metabolism, there are a lot of environmental free radicals attacking our skin that pushes the aging process along. By arming out skin, and our bodies in general, with enough vitamin C it can help slow down that process and in some cases help repair it to a degree. While you’ll now see vitamin C added to face creams and beauty treatments, you can also do a lot of good with a daily glass of warm lemon water.
Anti-Bacterial – Have you ever seen a person at the grocery store or in a tollbooth wiping their fingers on a half a lemon? Many people who handle money will use the lemon juice to wet their fingers to make the money easier to handle. There’s another reason, however. We know that the acidity from the citric acid and vitamin C of the lemon juice acts as a natural anti-bacterial agent, and frankly, who knows where that money’s been? Many people even use lemon juice as a disinfectant due to its anti-bacterial properties, but scientists say that on a large scale it may not truly kill all types of bacteria. The acid in small amounts of lemon juice have been shown to kill some bacteria, but its real strength lies in creating an atmosphere where they just don’t want to reproduce and grow. So think of the lemon juice or lemon water on your hands or fingers as a really great retardant for common bacteria.
Cancer – Can lemons cure cancer? No, not as such, but studies have shown that people with a high vitamin C intake do have lower instances of some forms of cancer. Plus we know vitamin C works against those free radicals in the body that attack our cells. Seriously damaged cells are those that lead to cancers. The citric acid in lemon juice shouldn’t be ignored either; not only does it help battle free radicals, but it is a compound that acts as a catalyst for the absorption of other essential vitamins and minerals in the body. So not only is it healthy in its own right, it helps the other healthy things you eat do their job.
Diuretic – Lemons are one of those foods that can help the body flush out extra fluids, and that’s helpful for many reasons. It can help lower blood pressure and ease a case of uncomfortable bloating. Over the counter diuretics do the job, but often they deplete your body of other things like vitamin B in the process. Lemon juice doesn’t work that way. We know that on the whole, lemon juice and its citric acid like to help the body keep and metabolize what’s good for it. Many people claim that lemon juice helps them lose weight – likely due to the loss of excess water, but it must be stressed that although darn healthy, lemons cannot be directly correlated to long-term weight loss. Think of them as a big picture health tool.
Detoxification – Many people have heard of the lemon juice, maple syrup and cayenne pepper cleanse. That is a serious concoction that should only be considered with doctor’s advice. On a more day-to-day preventative level the ingredients in lemon juice can help keep your kidneys and liver functions on the right path. The juice and oil from the peels contain a compound called d-limonene. It acts as an antioxidant that activates enzymes in the liver to fight against and break down toxins. In the kidneys the citric acid in the lemons help fight kidney stones. Again it’s the acids that help correct the alkaline levels, combined the boost it gives to binding calcium that helps your kidneys flush out the right things. Here too, think of lemons in the big picture as part of your healthy diet and not as a magic cure all.
Electrolyte Replacement – When you exert yourself or when you are sick, your body loses important salts, minerals and acids. All of these are important because they contain the ions or the electrical energy that helps your body work properly. The electrical energy communicates instructions back and forth between your cells and neural pathways. While there are many products on the market, you can make your own electrolyte replacement with lemons. Lemon juice also contains calcium and potassium, and those combined with the acids help speed the replenishment of the lost minerals and resets your pH balance. A quick recipe is 32 oz. of water, a pinch of salt, 16 oz. of lemon juice and a half a teaspoon of honey – which adds some sweetness and glucose to speed up absorption of the replenishing compounds.
Insect Repellent –Instead of using chemical sprays to ward off insects, lemons may again provide a natural alternative. Mosquitoes are particularly attracted to sweet smells and warmer temperatures among other things, but they do NOT like the sour citrus scent of lemon. It’s the essential oil of the lemon that is projecting the strong smell so you can make a natural solution of lemon oil and water and wipe yourself down to stay cool and bug free. Be careful though; the essential oil of the lemon is so strong it could irritate some people’s skin so be sure to test your level of tolerance and mix the oil with water or a non-scented cream. It’s no joke to ward off pests like mosquitoes – they carry West Nile Virus and other diseases that are serious health risks above and beyond being itchy.
Nausea – Surprisingly, for some people sipping lemon water can help stave off nausea. Citric acid helps neutralize troublesome gastric acids, much like popular antacids. Again it’s all about that balance between alkaline and acid, and citric acid can act like a regulator to even things out. It’s not a treatment that works for everyone, and should be tried in moderation as too much of the citric acid can create an upset stomach in its own right.
Stress relief – We shouldn’t underestimate the importance of stress in our overall health. When we are stressed all our systems are knocked out of the balance our body needs. As we’ve learned from the facts above, lemons and the compounds within them love to keep body systems in balance. Plus, the acids in the lemons – ascorbic acid and citric acid help boost the immune system by amplifying the effect of vitamins and minerals you are taking in from other foods. They are like tasty little bundles of peacemaking compounds for your body. Then there is the citrusy smell. Lemon oil has been used in aromatherapy for centuries for its relaxation and calming properties Some sources believe the smell of lemons has the ability to stimulate you and make you more focused and productive, so don’t be surprised if you see some people using a citrus scent at their desks to give them an edge.
The takeaway is lemons are remarkable fuel for the body. Their powerful compounds act as a regulator when needed to reset the body’s pH balance and make the environment for bacterial growth and toxins unfriendly. Amazingly they also boost other vital vitamins and minerals so your body gets to a more overall sense of well being.
So take those versatile lemons and add the zest to your diet or start your day with a warm cup of water with lemon. All things in moderation so don’t go crazy with these simple little fruits. Just augmenting your daily diet with a little bit of lemon can bring a bigger picture of good taste, good health, and a good sense of well being.
Some day in the future, science may find a way to harness the power of these fruits to provide targeted cures, and there is no doubt they are interested in what they see. But until then, just enjoy your lemonade.
A 7.1 magnitude earthquake hit the Pacific just between Papua New Guinea and the Solomon Islands on Thursday. This follows on the heels of the 7.8 quake in Nepal. A look at daily activity shows smaller quakes happening all over the world, especially in the infamous “Ring of Fire” region around the edges of the Pacific Ocean where tectonic activity is especially high.
What is happening when these earthquakes hit? Though it might not feel like it to us, the crust and mantle –essentially the “skin’ around the earth’s inner cores are always slowly moving. The pieces that make up these layers are bumping up against each other as they travel; the areas where they make contact are called fault lines.
When two plates of crust get stuck against each other, the energy of the movement builds up. Eventually that stored up energy is released with force when the two pieces finally come unstuck. The location where the energy is released is called the hypocenter under the surface of the crust, and the epicenter on the surface. The energy released heads outwards from the center, shaking the earth in waves.
One plate may slip up while the other slips down under the other in what’s called a subduction zone. In fact, in the case of the recent Nepal quake, the way the two plates came to rest caused Mt. Everest to lose height! Subduction zones often become areas of heightened activity.
One of the most challenging things about earthquakes is the drama isn’t over after the “main” shock. After the initial devastation at the epicenter, the earth is still settling and reshuffling itself into place causing further shakes called aftershocks. Some can be quite severe, frequent, and go on for extended periods of time – even years. It’s what makes recovery in remote areas quite hard to manage. Buildings and infrastructure have become unstable and more susceptible to the rattling – even if it is of lesser magnitude.
So can we predict earthquakes? The most reliable answer is to say not definitively. There have been cases in China where monitoring set up in high-risk regions have recorded questionable activity and given officials time to evacuate. However, just as often a quake will come with no warning at all.
The earth is unpredictable. While we have become extremely knowledgeable over the years about where trouble zones are for earthquakes and volcanoes around the world, we still don’t have a full understanding of when devastating events may occur. Fortunately, there are scientists and researchers all over the globe studying the earth’s hotspots with a keen eye, and those who head into the devastation afterwards to gain clues that might help us create informed, reliable warnings in the future.
We hope you’ll find deeper answers in our playlist above, all about when the earth makes its moves.
Next time you're trekking through the rainforest in Guyana, look out for a spider the size of a small dog.
Entomologist Piotr Naskrecki spotted the massive South American Goliath birdeater (Theraphosa blondi) on a nighttime walk through the rainforest. As he writes on his blog,
"Although far from being the largest member of the subphylum Chelicerata – this honor belongs to horseshoe crabs – Goliath birdeaters are ridiculously huge for a land arthropod. Their leg span approaches 30 cm (nearly a foot) and they weigh up to 170 g – about as much as a young puppy."
When Naskrecki approached the creature, as detailed in his blog post titled 'The sound of little hooves in the night,' the spider "would start rubbing its hind legs against the hairy abdomen" and made a hissing noise.
