Rezonant's guide to funnelwebs: care, venom and other info

Hey @RezonantVoid do you by chance have any source material regarding H. formidabilis being more potent than A. robustus? Otherwise LOVED the post and thread!

Everything in this thread, from husbandry to source material, needs overhauling, the husbandry quoted is the awefully barebones simplified method used for the majority of tarantulas and I have found far better solutions that suit both spiders and aesthetics, I will be making a megathread for all Australian mygalomorphae care along with source material.

You'll have to take my word for it for now, but it's not just formi that are more potent than A.robustus. Hadronyche as a whole have different venom structure and both sexes share equal levels of toxicity as opposed to Atrax where the males are the ones with elevated potency. This is also the reason why Hadronyche cannot be used for antivenom milking, and only compounds from Atrax venom can be used instead

@RezonantVoid Yeah it figures. I remember you've talked about different substrates and such in you mygalomorph picture thread - it's fantastic that you're sharing it all.

Yeah, that's what I've read too, but I've been unable to find any actual studies that prove it. I'm not disbelieving it, I take it in light of not knowing how to find it.
I don't get why Hadronyche species cannot be used for milking - in spite of the differing venom composition, the anti-venom is used for Atrax is also used for Hadronyche?
But it's interesting that Atrax robustus seems to be regarded as the world most venomous spider, while it appears to be commonly known - at least in some circles - that Hadronyche is more potent. Especially with H. having equally potent males and females.

I'll look forward to your updated thread, whenever you do it.

It's puzzled me too, but I think one thing they beat Hadronyche in is being the most dangerous funnelweb. Formidabilis and infensa may have higher toxicity and cerberea might have higher envenomation rates, but Atrax robustus location puts it in regular contact with humans, meaning a bite from them is more likely to occur than let's say a formidabilis that normally live 30m up trees in less populated areas. So I could agree that robustus can be considered more dangerous regarding likelihood of a bite, but definitely not the most potent. Some Phoneutria overseas could have even stronger venom than all of these, studies on which I'm extremely keen to read
