Deep in the Congo jungle, a species of spider is said to exist that can grow up to 5ft across. Entomologists and arachnologists claim that this is impossible because of a spider's respiratory system being too inefficient or something like that. The question is that if these spiders do exist, what evolutionary advancement have they attained that allows them the exceed the proposed spider size-limit?
Honestly. The way spiders are put together doesn't really work for giant versions. The bigger it is the more weight which means the thicker the legs which means the body has to be more powerful and so on and so forth.
Another thing is spiders move through fluid hydraulics if I remember right and I don't think that would scale up well either.
A giant insect wouldn't be an insect at all. It'd be something else. They'd need to have muscle and bone and all that kinda shit.
The reason Arthropoda dent eyed a certain size is that exoskeletons are shit at carrying very much weight. These spiders would require a highly advanced circulatory system, exoskeleton and respiratory system in order to even live let alone hunt.
Oxygen levels are not high enough for insects, and arachnids to grow huge like they used millions of years ago. Something like that.
Also anyone else having a hard time posting? Im doing th captcha right, but it keeps saying i didnt do it.
Coconut crab. Slow, herbivorous and not an apex predator.
Lives thousands of feet below the ocean, doesn't have to support its own weight, eats stuff it doesn't have to catch.
Sorry folks, there's no way it'd happen. Square-cube law holds true in biology as well.
insects do have muscle, but they wouldn't work on a larger version because of the exoskeleton proportions. think of a giant duck: the legs would simply break, because when you upscale size you do a ^3 in volume and not necessarily a ^3 in resistance
Spiders arent necessarily active hunters, that the exception not the norm. Not saying you dont have points but the whole not an apex predator / has to catch its own prey angle is flawed.
Smaller spiders arent apex predators either, think different go ask ants and wasps.
Deep in ancient japanese history, a species of crab is said to exist that can grow up to 5ft across. Ichthyologists and crustaceologists claim that this is impossible because of a crab's weak point system being too inefficient or something like that. The question is that if these crabs are actually based on actual battles that actually took place in ancient japan, what evolutionary advancement have they attained that allows them the exceed the proposed massive damage-limit?
Oh yeah that one is real, just very rare and aggressive so they won't tell us.
Also if they were to just tell us all the cryptids that actually exist it would cause mass hysteria.

>word gets passed around of giant man eating spiders and a legend is born
Same thing with how a lot of monster legends start. You have a settler in early America see a grizzly bear, he tells everyone he saw a giant fury beats with claws, sharp teeth, 9ft tall and could kill a man and bam you have some spooky monster stories
Even so ancient spiders were as big as the biggest ones today are, at best.
This anon semi knows his shit
Arachnids have book lungs and those are shit outside of water
Still a novel idea and makes for some good spooks
Not necessarily apex but stupidly efficient killing machines when they want to be at least.
Depending on what type of spider it is, at that size, it would either have to be hella fast or hella poisonous.
>tarantula owner here
If you look at arthropods, you see generally the larger they get, the slower they get. At some point they are too big to be effective out of water, so that's where most of them larger than a hand evolved to live. Where is the breaking point between a massive arthropod able to predate on land with and sort of movement and just being a different animal? The press of evolution never really squeezed one out in current atmospheric conditions.
>Another thing is spiders move through fluid hydraulics if I remember right and I don't think that would scale up well either.
This is wrong.
Musculature based on compressing fluids would scale up pretty well, and could serve as psuedo-bones as well. They'd still require normal muscles around the bladders, but the bladders themselves could exert a lot of pushing force, which regular muscles aren't great at.
>carry your own butter sauce into which your flesh after you have been cooked alive can be dipped
>people still argue against intelligent design
This giant fucker was put on this world by god for man to eat and lose his fingers to!
'explorers' weren't these pampered pussies who shrieked at the first sight of a bug. These were some of the most hardened realists of their era, actually experiencing the wild for what it was and not sitting in the comfort of the city. I'd sooner believe a journal entry of a proven man like Percy Fawcett than the speculation of 'scientists' who have never been out in the field.
I want to believe that dinosaurs survived.
We mustn't overlook the cephalopoda threat.
We talking about this here?
> 1938: Congo, Reginald and Margurite Lloyd were driving a Ford truck through a trail when they reportedly spotted a spider as large as a monkey. It resembled a tarantula, but had an estimated leg-span of 5 feet.
>"This article relies largely or entirely upon a single source."
Are you fucking serious, you can't use that as a- Oh shit, sorry, I forgot where I was.
Carry on, autist.
>respitory system being too inefficient or something like that.
That is true of literally every living thing on the planet. That's why things were bigger when the atmosphere was thinner in ye olde prehistoric time....the thing atmosphere compensated for everything's shitty ability to process air.
The atmosphere was just as thick and more rich in oxygen.
That's why insects had to be so big since they breathe through their skin, bigger dimensions, less surface per mass. Smaller ones would actually get too much oxygen.
The opposite of correct. Back in't day the atmosphere was thicker and oxygen enriched.
This meant that every haemoglobin molecule in the blood was saturated with oxygen and there was also unbound dissolved oxygen independent of the haemoglobin also in the blood.
Read about deep diving and nitrogen narcosis for a better understanding of ventilating under pressure.
Also, guys, what about a symbiotic relationship between a giant spider and an ATP producing skin parasite? Then it wouldn't need a top notch circulatory system as the external microbes would produce the ATP 'on site' so to speak.
Offer a counter argument if I'm wrong but due to an arachnid's way of growing (ecdissys) this wouldn't work
If this fungi penetrated the skin to where it was present on both the outer layer (protective hardened exoskeleton) and the inner (the one growing under) then this would create weak "spots" on the spider's skin. This would be susceptible to infection and just plain old physical force which spiders today are already very sensitive to. This sounds like a shitty trade off to me.
Yeah because bears were totally unknown to Europeans before that.
It could be some sort of a animal that diverged from spiders. But since spiders internal workings are trash tier for big stuff it would probably have to have a endoskeleton and a muscular system, along with a bunch of other stuff
unless the exoskeleton is permeable to ATP, no idea of the relative size of ATP vs spider bone pores, not a spider expert. In fact, I fucking hate spiders, those guys are bastards, I hope they can't grow big!
>a nigger with eight rakes,
>doesn't make a spider,
>EVEN IN THE DARK.
deal with it.
Well, let's think about what would be required:
>exoskeleton would become redundant and a suitable endoskeleton would need to develop, as they wouldn't be able to survive during a molt if they were relying on an exoskeleton to support themselves
>legs would need to be much thicker and grow straight down, or it would literally do nothing but drag itself around because it takes too much energy keeping itself up
>respiratory system would need to change from simple book-lungs to lungs more like a mammals, to allow for greater gas exchange
>musculature would need to change to suit an endoskeleton over an exoskeleton
>look at me I know what an arachnid is
>now's my time to show everyone I'm not a fucking retard with my elementary school knowledge written in the most meme way possible
>yay! I'm smart!
Those "giant spiders" have too many amazing qualities to exist solely in some remote location, and it's such a evolutionary breakthrough that you wonder why only some spiders have it
As much as I'd like Giant Spiders, they are not happening
Maybe they're cyborg crabs created by gas demons by mixing bacteria with rapid-evolution juice
Giant bugs did exist once.
As well as 2 feet long scorpions
But that was due to the fact that oxygen content was much more concentrated back then.
Something that makes giant insects impossible today. Since the size of invertebrates is directly dependant on that.
spider being defense force detected
this interview clearly lays out the fact that ancient race of spider beings created and control humanity and in fact all life on this planet.
all living organisms breathe
>said to have existed
perhaps they never did?
spiders and insects breathe through vents between their legs. larger organisms need hears and lungs to transport the oxygen through the body. a 1.5M spider wouldnt have been a spider
>species of spider is said
People say a lot of things, that doesn't mean they're true. Jordan Pearce says that Jews are from space and the moon was placed in orbit by ancient aliens, for example.
i read somewhere that this pornstar claimed that she was in some weird japanese underground porn thing, and like women were being fucked by dogs and other animals, and she claimed to be fucked by a giant spider.
Anyone else read this?
>be crazy fucking jungle bunny
>decide to fuck rest of africa by making giant spiders
>train spiders to come to me once a day through selective breeding
>give them a bunch of oxygen to make them grow larger over generations
>release 6 foot wide spiders upon africa
They showed pictures of different animals to the tribesmen who report the existence of Mokele Mbembe. Without exception and without delay, they all pointed to the picture of the elephant. An isolated species of forest/jungle elephant, that's all it is.
Not just any dinosaurs, they're the dinosaurs that were badass enough to survive the dino apocalypse.
They don't have to be big to be smart. The Portia spider not only exclusively hunts other spiders (often far larger species), but is capable of creating and even modifying unique hunting and trapping strategies for each individual species, including pretending to be trapped in the prey spider's web and even performing the mating dance of another spider species. It can also remember successful strategies and reuse them when faced with another spider of the same species as past prey.
