The aptly named goliath bird eating spider (Theraphosa blondi) is an alarmingly large and hairy tarantula native to the Amazon, stalking the upland rainforest regions of northern South America. Females, who traditionally eat the males after mating, can live for up to almost 30 years and grow to nearly a foot in length. This officially makes them the second largest spiders in the world and arguably the largest by mass.
