Brazilian wandering spider

Brazilian Wandering Spiders are extremely fast, extremely venomous, and extremely aggressive. According to some researchers, this is the deadliest arachnid on the planet. The Brazilian wandering spiders can grow to have a leg span of up to 13–15 cm (4–5 in) and their body length ranges from 17 to 48 mm (0.7–1.9 in). In South America, these true spiders are commonly encountered in peoples’ homes, supposedly hiding in peoples’ shoes, hats, and other clothes. The Brazilian Wandering Spider does not remain on a web, rather, it wanders the forest floor, hence the name. Sometimes they are found in crates of bananas and they are shipped all over the world. For this reason the spider is also Banana spider and many shipments have to be closely watched. The Brazilian Wandering Spider is actually the generic name for eight species of spiders that belong to the genus Phoneutria – Greek for “murderess”.

Bites in humans

Authoritative sources state that over 7,000 authentic cases of human bites from these spiders have been recorded, with only around 10 known deaths, and about 2% of cases serious enough to need antivenom. Symptoms to look for when thought to have been bitten includes immediate pain, cold sweats, and heart irregulaties. The bite is very painful and it’s highly recommended that look for medical assistance right away.
Aside from causing intense pain, the venom of the spider can also cause erection in humans. Erections resulting from the bite are uncomfortable, can last for many hours and can lead to impotence.
