chrisr- sorry bud, I believe you are incorrect. all arachnids posses the means to inject their venom into animals, including humans. it is just that the venom is either so weak or the arachnid injects so little that it is not dangerous.
define “most venomous.” do you mean the one that injects the most venom, the one with the most potent neurotoxin or the most potent hemotoxin? or the one that bites humans the most?
anyhoo- thems some big damn whatever the hell they are in the pic. I wonder how they taste…
