I'd like to observe, that although funny and drawing a lot of attention, this thread is wrong.
Spiders ARE poisonous. Plenty, if nost the most of them, really. By default we simply do not consider them food, but they are eaten in some parts of our world, nevertheless.
And yes, spiders, ar least some of them are venomous.
Omg that's really interesting, I never would have guessed! Are the effects of the venom and the poison similar at all? I kinda had the intuition that venoms were generally at least kind of edible, probably just because snake venom is lol. Is it even the same chemicals between the two effects? Sorry, my mind is just blown, haha
There are many toxins and some might produce similar effects when ingested, to those that were injected into the bloodstream. Some among these are similar to alcohol poisoning, some might probably give you a drug-like bad trip, others might be fatal. What I'm trying to say is, that there are many variables involved and the result "might vary".
I can't provide you a source that you'd probably accept on the spot, since plenty of these, including scientific ones use terms "venomous" and "poisonous" interchangeably. I can direct you to the entry in Wikipedia, that lists mere 15 edible species of spiders, instead of saying "pretty much each and everyone is edible":
Now, I assume you're thinking "I can swallow a spider and it won't kill me, therefore they can't be considered poisonous". This isn't true. You CAN eat plenty of spiders and you will absolutely survive it. You may even not suffer much problems because of that, like stomach irritation, or diarrhea, but that's because the poison they contain isn't powerful enough to seriously harm you.
Side note: an "interesting" thing may happen if you eat a venomous spider, while suffering from an open wound in your digestive system. I think there was an episode of "100 ways to die" dedicate to this idea. Or was it snake's venom?
My good dude, what I said is correct and you're going to hear it from me every time the topic of eating spiders is going to be brought up. I simply can't find it in myself to waste the rest of this evening trying to convince a guy who expects argument, not a discussion.
Feel free to treat it as "a win" or whatever suits you.
I ate spiders where they are served as a meal. And I still enjoy their companionship. This does not and won't prevent me from pointing out that they are indeed poisonous - plenty of them in fact.
It's the same thing as with certain mushrooms. The dose makes a poison. In case of spiders, eating one or two won't do you much harm.
