Brazilian wandering spider

Phoneutria_nigriventer.jpg (102 KB)

“Phoneutria nigriventer venom contains a potent neurotoxin, known as PhTx3, which acts as a broad-spectrum calcium channel blocker that inhibits glutamate release, calcium uptake and also glutamate uptake in neural synapses. At deadly concentrations, this neurotoxin causes loss of muscle control, and breathing problems, resulting in paralysis and eventual asphyxiation. In addition, the venom causes intense pain and inflammation following an attack due to an excitatory effect the venom has on the serotonin 5-HT4 receptors of sensory nerves. This sensory nerve stimulation causes a release of neuropeptides such as substance P which triggers inflammation and pain.”

Can also cause 4+ hour boners.

    Can also cause people to burn it with fire.

    I like spiders, but that shit is scary. Poisonous spiders aren’t supposed to get that big. At least, ones that can harm humans anyway.

    Spider is obviously defanged. Otherwise that guy would be screaming in pain and the spider would still be trying to bite him and inject even MORE venom into him unless he managed to kill it.

    Really? I’ve seen a guy handle a funnel web spider, and those things give me the willies.

    Enjoy when the cells in your dick begin to rupture and you get it amputated from gangrene. Also, that 4+ hour boner? EXTREMELY PAINFUL.

    These guys are commonly considered the most venomous spider on the planet. To make things more interesting, they’re extremely aggressive, have been known to actually chase people down, and rarely give dry bites.
