Deep in the Congo jungle, a species of spider is said to exist

That's bullshit, only primates breathe.

>>17207809
Sounds like some 8-legged freaks bullshit

>>17207809
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.

>>17207809
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.

Possibly. I imagine if that much foliage was producing CO2 instead nothing would survive there long.

Coconut crab. Slow, herbivorous and not an apex predator.
>>17207994
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.

All the spider would have to evolve in order to make this possible is an efficient air pump. Basically, lungs.

I believe. Where can I hear about this myth??

>>17207809

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

>>17208130
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?

>>17208862

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

Depending on what type of spider it is, at that size, it would either have to be hella fast or hella poisonous.

... giant smart spiders

>>17208404
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.

Maybe it's not really a spider but some other cryptoid that looks kind of like a spider but those dumb savages just think they're giant spiders.

>>17209800

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.

You clearly have no idea how hydrostatic pressure works.

>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.

>>17213792
Not exactly.
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.

>>17207809
what if they have endo and exo skeletons?
I feel /sci/ or even /an/ would be better suited to explaining this sort of giant spider theory.

>>17207989
seconds before that dog was ripped to shreds

>>17213792
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.

>>17207838
Wow, I don't even begin to herp till somebody derps this badly.

>>17213844
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.

Well, let's think about what would be required:

>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

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.
