Sean Duggan travels to Costa Rica and comes face-to-face with a monster born from the jungle--the Brazilian Wandering Spider. Considered to be one of the deadliest spider species known to man, this six-inch arachnid packs more poison than any other spider in the world. This lethal spider can travel many miles in a single year, following weather to favorable habitats. Recently, the Brazilian Wandering Spider has been reported as far north as Costa Rica, and Sean is here to investigate if these sightings are true.
