A spider in Brazil can cause erections that lasts for hours


The Brazilian wandering spiders appeared in Guinness World Records 2012 as the world's most venomous spider. Its venom can cause priapism in humans. Priapism is a potentially painful medical condition, in which the erect penis or clitoris does not return to its flaccid state, despite the absence of both physical and psychological stimulation, within four hours. A component of the venom (Tx2-6) is being studied for use in erectile dysfunction treatments.

The eight-legged creature - also known as the armed spider, banana spider or Phoneutria nigriventer - is native to South and Central America.
