The Brazilian wandering spiders, also called armed spiders, appear in Guinness World Records from 2010 as the world's most venomous spiders.
The species Phoneutria nigriventer exists in Brazil, Uruguay, Paraguay, Argentina. Its bite is venomous and painful, as expected.
So what @rmach? We know you bring us useless information but this is beyond useless and has nothing interesting.
Ok, you asked for it.
The venom can also cause...
...long lasting erections.
Don't get creative!
It's so long (and uncomfortable) that can even lead to impotence.
The venom is being studied for erectile dysfunction treatments.
See you tomorrow for more “Useless information”
