In South America, so-called wandering spiders (Phoneutria spp.), which attain a legspan of nearly 12 cm, are reputed to be deliver a bite of rare potency. A side effect that may interest some is a "painful and prolonged penile erection" that can last for hours with no happy ending. Aptly enough, the beasts are also known as banana spiders for their habit of hiding in bunches of yellow fruit.
Ctenids in this part of the world, however, fail to reach the sizes of their New World cousins. Likened to enormous lycosids that "roam aimlessly (often in a dozy fasion) over the leaf litter", these heavily-built spiders display a bright-eyed affability when disturbed from their nocturnal constitutionals. Even when (gently) poked, the creatures are quite unperturbed and simply amble to a nearby blade. It's a frustrating brush for those who seek to test the theory that one does not need to go all the way to Brazil for close encounters with women who test your hardness before they bite off your head and break down your heart.
