Most VENOMOUS Spiders in the World - Reaction

[@domvasta]

I have had a bite from a wolf spider, she was my 2nd ever "pet" spider, I'd caught huntsmen before and fed them roaches then let them go in the bush down the road, but she was in my shoe, (I had squashed her right front leg so I thought I needed to rehabilitate her, she grew it back when she molted) but strangely enough she didn't even bite then, when she was being squashed. She bit me when I had given her a cricket before I went to work, then when I came home, she hadn't moved, and the cricket was hopping around, so I thought she wasn't hungry and it was stressing her out, so I figured I'd grab it out with my fingers, because they're a bugger to catch with forceps, she actually was hungry and was just not interested in chasing the cricket, so when I put my fingers around the cricket, she ran out and bit me, probably thinking I was the cricket. The bite was less painful than a papercut, the venom was interesting, for about 20 minutes I had an elevated heart rate and was sweating a lot and had a headache, then about an hour later, as I was driving to the Gold Coast, I suddenly felt really intoxicated, like I was drunk, which made drive faster, because I wanted to get to the hospital if this was going to last. I work in a pathology lab and I got toxicology to look at a diluted venom sample I managed to get from getting her to bite a pipette, nothing in the venom that fit the symptoms, so I moved to immunological reaction to the venom, I think the antibody response caused the issue, one of the peptides in the venom shares part of it's structure with the GABA receptor γ2 subunit, which is the binding site for allosteric modulators of GABA, like benzodiazepines, so any antibody produced in response to the venom, could bind to that site too, producing similar effects. I want to do this stuff for my PhD, look at the immunological responses to other venoms, I've been developing antibodies by injecting myself with small amounts of spider venom, or coaxing spiders to bite me, depending on how venomous they are, no other spider has produced the same effect. Huntsman bites have produced an effect of making me urinate a lot and keeping me very alert and focused, but these all have therapeutic potential, with the technology we developed, we can take the spider's venom genes and put them into an mRNA vaccine, giving long term effects, if you could make a non-addictive anti-anxiety drug that you only have to take once every few months, that would save so many lives in terms of overdose prevention, black market diversion of medication and addiction, even if it was addictive, getting an injection every few months is a lot less of a burden than taking pills everyday and would probably make people less scared of spiders, both due to the fact they're associating spiders with helping them, and the fact that their fear response is lessened by the anxiolytic properties.

A Wolf Spider is sadly monstered for some reason...🤷‍♂️

[@axxomovies-he6zi]

Steatoda Nobilis has very similar (medically significant) venom to black Widow. But try getting one to bite you! Not an easy task!. There are so few actual spider bites that are full on not just defensive dry bites. Compare the amount of spiders to people on the planet! It's basically negligible. Spiders venom is complex and very small. Like finding the ten most venomous is almost impossible and finding any that pose a threat to humans even less chance. They aren't even trying to catch us. So we can look at venom and guess what it would do but for the most part humans aren't getting bitten enough to have any real idea imo.

[@cjthebeesknees]

Yooo Dom, dig your dedication so much from taking the bites and injections of venom yourself to thinking outside the box and of humanity and how you can develop treatments and such, much respect brother.

It's true that no one has died Ever since they made anti venom, But people used to dial the time from the Is funnel Web spider before anti venom.

The wolf spider’s inclusion is something I can’t understand!

[@BugsandBiology]

Nice to see Torryn is back to celebrate the 7k subscriber milestone.

[@BugsandBiology]

Yeah there really isn't any justification for including them on the list. I mean, he even said their venom is pretty mild.

[@cds3703]

It actually takes a lot to make a wolf spider bite. I have 3 and i’ve handled all of them and no bites at all. But then again bigger species like Hogna carolinensis are food aggressive and may bite someone thinking they’re food, but again, if they realize you’re not prey they leave you alone

[@westerncleverly]

If you go out to bush and find damns and lots of grass and wear a head lamp you can see the reflection of hundreds of them sometimes in an area, one damn I went to marroning at night I had to walk around the water and I saw hundreds and they were very placid and not ravenous or anything it was fine and peaceful, I think if I had to sleep in a swag on the ground there I would hope it had zips but still they wouldn’t bite you I feel. Nice spider they are.

[@dirkvandermerwe6027]

A wolf spider do not earn it's reputation...

[@westerncleverly]

Amazing video. I just saw a mouse spider walking across a track between wave rock and hippos yawn in Western Australia. It was raining heavily that day and when I got there it had just stopped. I am from WA living close to the city and had never seen this spider before so I was amazed. It was beautiful. I looked closely and kept on my journey. Only after googling it and identifying it by the photos I had taken did I realise its venom to be that similar of a Sydney funnel web spider, well I was far too courteous to take up too much time of this spider to find out and I’m glad they can’t jump (I got close for a pic) but I’m very grateful to have seen one for myself, if much of the beaten track

Wolf spiders are a spider I will go out if my way to protect as well as a golden orb weaver aka banana spider. I woke up from a dead sleep to a spider crawling on me and managed to move slow enough to turn the light on to see a wolf spider. I made sure my fiance didn't kill it. Sadly the little guy 2 days later ran under his foot. 😟 he nearly fell down trying to avoid him but he didn't make it. I love those 2 spiders. I won't play with them but I will respect them.

[@jaymorales5049]

The difference between you and that Tool is that you have a passion for Arachnology where that other dude just Googled a bout spiders and found the most scary looking and made his list. Your very under rated.

[@ayemjake]

The potency for the Lactrodectus venom (as per from what I've gathered, take this with a grain of salt) puts the Brown widow above Black widow, HOWEVER, the amount of venom they can pump out is significantly smaller, so small in fact that it poses little to no danger to humans. Side Note: Despite the very little study of Six eyed sand spider, I think its venom potency kinda makes sense to me, since these guys can sometimes live up to a year with no food in sight, and in a place where food is scarce, having a powerful weapon could mean the difference between starvation and securing food. That being said, these little guys pose little to no danger to humans as they are very reclusive and tend to live in the most uninhabitable places for humans.

Brilliant video very informative as you always make them generally I love Richards videos are very good very informative but most of all he doesn’t scare monger about things which are a lot of top tens do. It would be interesting to find out what your top 10 deadliest would be keep them coming I love it when you do these comparison videos

[@chazsaw]

While the katipo, NZ's redback, is thought to be descended from the Australian redback, to the best of my knowledge everyone agrees that they have speciated. I suppose it is possible that in some of the warmer parts of the country the redback have managed to colonise from fruit important, but I have never heard of it.

[@neodymium8936]

For Cheiracanthium, they actually have a pretty potent venom. I live in France, with Cheiracanthium punctorium, and the venom of the males can cause nauseas, headaches, and their bite is very painful. You say they have mild venom, which is technically true, but in France they are among the spiders with the most painful and venomous bite.

[@chrisy4011]

1983 was the last known death from black widows. Due to lack of antivenom and technology.

[@dirkvandermerwe6027]

Set aside the major button species as in the: Black & Brown Widow, Red Back, Ausies's Funnel Web species including the Mouse Spider - majority of other so called medically significant spiders' bites are treated as severe due to secondary infections...

[@JackFrostIsHere]

*Sydney Funnel Web spider comes easily at number 2 though. It has been proven several times that its venom much more potent than that of Brazilian Wandering Spiders due to the fact that it's not just lethal but also has the highest acting venom in the entire animal kingdom (can even kill in just 15 mins!) The wandering spiders are deadliest because they come in contact with human habitat very often causing unexpected events & hospitalisation of people. Sand Spider comes at number one because to this day no antivenom has been invented for its necrotoxic venom meaning the only way to survive from death is by amputation of limbs. But six eyed sand spiders are very shy and timid little creatures living in harsh desert environments where humans and animals rarely come across hence very little reported cases*

[@BugsandBiology]

Can you cite any sources for the “highest acting venom in the animal kingdom” claim? That’s a very bold remark. Also the 15 minute death was a huge anomaly. Most funnel-web bites don’t even need antivenom, and for the minority that are fatal, they usually take hours to days to kill.

[@tylerblakeley2443]

[@willievankoolwijk2994]

Exactly what I was thinking 😏

[@chrisy4011]

Brazilian wandering spider and sand spider worst. Period.

[@BugsandBiology]

I'd honestly have a rather hard time coming up with a list, due to the reasons I specified towards the end of this video.

[@kimberlygabaldon3260]

I've been bitten by yellow sac spiders, and it stings, but that's about it.

[@BugsandBiology]

Yellow sac spiders seem to be the American version of white tails. A pretty much harmless species that's widely feared as a result of wild misconceptions.

[@kimberlygabaldon3260]

@@BugsandBiology The bites DO hurt, if nothing else. Here's my story: I had a 4-foot fluorescent ceiling light fixture in the kitchen of my old house. One day, i was sitting right under it, and felt a bite or sting on my shoulder. I looked, and didn't see anything. A few minutes later, i felt another sting on my arm, followed by another, then another. I looked up, and saw a little cloud of something floating down toward me from the fixture on the ceiling. I looked closely, and saw that they were tiny, pinhead, yellow sac spiders, floating down toward me on their little silk threads. There must have been a nest hatching in the light fixture. Even the tiny hatchlings packed a pretty good stinging bite, for their size. We had quite a few yellow sac spiders around, but it was the type of thing that I would shoo away like a bee, not freak out over. We also saw the occasional black widow, which was much more concerning. When i moved, I saw 5 or 6 black widows in the garage, within the first five or ten minutes of entering it. I was bitten by a black widow, my second night in the house. It started with cramping at the site of the bite, and soon felt as if someone was grinding a lit cigar into my hip, and I was sick for a couple of weeks, with shifting symptoms, but the first 24 hours were the worst. The first hour after the bite: severe pain, FREEZING chills on left side of body, shaking, gooseflesh. The pain was burning, with the feeling of electrical current along the nerves running toward spine and down leg, followed the next morning by nausea, shakes, palpitations, muscle cramps all over body. It also left a huge blister on left hip, that took a couple of weeks to go away. I did not go to the hospital, (wasn't sure about my insurance in new town, and didn't want to get lost trying to find my way at 2:00 a.m.), but it really was NOT pleasant. By the time i figured out the way to the hospital, i figured the worst of it was over.

[@pl1guru]

The Yellow Sac spider shows up in several North American lists (both of academic and more casual nature) of venomous spiders, but that is because there are a few studies that state the venom is necrotic and similar or more potent than the Brown Recluse. There are just not enough studies to prove it though, and the more likely cause is staph bacteria on the spider's fangs. Why Richard put Wolf Spiders on the list though, I really don't know, other than mechanical damage, and possible infection, they are pretty harmless. Mostly scary because of size and speed and not from venom.

[@johntowner1893]

Almost every wolf spider I see in Sydney will position itself on a hard smooth vertical surface, just above the ground, facing downwards… They have their legs outstretched, to sense for vibrations of something walking by bellow it. I saw a rather small species that I haven’t seen before, in Sutherland, Sydney NSW. It had sandy to light brown banding on the legs, and had very skinny legs and tiny abdomen, compared to its leg length. Just a bit larger than a 10c coin.. It was not a juvenile of the more common wolf spider I see around often. I rarely see them “wondering” or hunting like a wolf. One very cool thing I’ve seen late at night in the garden however, was a large wolf spider with in its fangs was a dead, slightly smaller but chunkier, dark black hairy spider, that I’m 90% certain was some species of funnel web or mouse spider. It would be about the size of a 20c-50c coin, while the wolf spider was at least 1.5x the size of a 50c coin. I got photos of it too and was very cool to see.

[@BugsandBiology]

Interesting! I have seen a pic of a wolf spider eating a trapdoor spider that, if anything, appeared to be somewhat larger.

[@katesims2346]

I'm Australian and to say red backs aren't common is nonsense. They are everywhere.

[@effy_kujo]

Nice, respectful video. While it's disappointing to see Richard making an ill-informed video, I presume he does these "top ten" videos in hopes of the video, ergo his channel, standing a better chance of being picked up by the algorithm. However, it's not an excuse to deliver misinformation. I truly like his species specific videos about the different tarantulas he keeps. To my knowledge he doesn't keep very many true spiders so, maybe he's not as knowledgeable in that area & this was a fluke. I'm assuming he found a few of those random top 10 lists on Google you love so much 😅 and picked the spiders that made the most appearances on average, just a speculation. Hopefully, if he sees your video he'll realize that he should have done better research. I don't usually watch his top 10 videos unless it's about his favorites or something that's more subjective.

[@saturniidmoff]

Drop for drop toxicity wise the geometricus is more potent than the mactans. As for size playing a factor I wouldn’t be able to tell you about that.

[@CentipedeGuy]

To me this video screams “ima teach some dummy’s who know nothing not to kill spiders and maybe get some of them interested by using a clickbait title that I won’t totally follow.” It’s the only rational reason I can think of for the wolf spiders inclusion. I think he just wanted a better entry video to spiders than all those awful top tens you usually react to… so he made a slightly better one…

[@effy_kujo]

Yeah, maybe. I was disappointed to see Richard here because, I do love his T videos. My speculation was that he does these more controversial clickbait top ten videos for algorithmic content though, it's not an excuse to deliver misinformation. I enjoy his more subjective top 10s, like his favorite old word Ts, new world, dwarf, etc. And his species specific videos where he mainly just talks about a T in his collection, his experience with it while getting to see some awesome footage of it. Love his camera work.

[@NorthEastSpiders]

Problem is, instead of making a "slightly better" one, he could have made a "much better" one simply by providing accurate info throughout. I suppose less lies is better than lots of lies, but no lies is always best and there is literally no reason not to just spread the truth when it comes to spiders, already way too much misinformation out there without so called "experts" just adding to it.

[@CentipedeGuy]

@@NorthEastSpiders I mostly agree, but he didn’t do it with any malicious intent, he mostly just made small errors that where honest mistakes and pretty harmless, except of course the title and his picks but if that was accurate it would be a pretty boring list of different funnel web subspecies.(that’s a joke, but… it is a bit true.)

For Australians, a lot of them seem to think they get bragging rights from the funnel-webs’ “deadliness”, to the point where they’ll get surprisingly offended when one points out that they aren’t as lethal as widely believed. Might be a similar mentality for people who live alongside black widows.

@@BugsandBiology T. vagans is put in the list because they are surprisingly defensive for a NW tarantula that was previously part of the Brachypelma genus, one of the "best for beginners" genus of tarantulas. They have a much higher tendency to display a threat pose and kick hairs compared to the other Brachypelma and Tlitocatl species. Sure every individual is different, but some species have a higher tendency to be defensive than others.
