#1 - The Brazilian Wandering Spider
The Brazilian Wandering Spider is a large brown spider similar to North American Wolf Spiders, but bigger and possessing a more toxic venom. It has the most neurologically active venom of all spiders, and is regarded as the most dangerous spider in the world. Brazilian Wandering Spiders are active hunters and travel a lot. They tend to crawl into cozy, comfortable places for the night and sometimes crawl into fruits and flowers that humans consume and cultivate. If the spider has a reason to be alarmed, it will bite in order to protect itself, but unless startled or aggravated, most bites will be delivered dry (i.e. without venom). Venom bites will occur if the spider is pressed against something or hurt. In this case, the high levels of serotonin contained in the venom will deliver a very painful bite that can result in muscle shock. Survive any wilderness situation with these critical tips.
