What are the symptoms of the Brazilian Wandering spider?

Answer 1

The symptoms of the bite of the Brazilian Wandering Spider are (1) immediate intense pain because the venom contains lots of serotonin, which affects the human nervous system, (2) local inflammation, (3) intense penile erections (which can result in impotence if not treated promptly), (4) general interference with the central nervous system (some components of the venom are neurotoxins) resulting in loss of muscle control, breathing problems, asphyxiation. (5) death unless the spider gave a small injection of its venom or antivenom was administered in time.

This venom is generally regarded as the most toxic of all spider venoms. It is fortunate for humans that these Spiders bite defensively and will generally stop biting and delivering venom when the spider no longer perceives itself to be threatened.
