some venomous critters can't hurt you because of some natural impediment...some very venomous spiders have legs too long to get a bite of you.
The Goliath Bird Eating tarantula lives in the tropical forests of South America. They are the largest species of tarantula in the world with a leg span of ten to twelve inches. The spider is very large and stocky with a hairy, coffee-colored body. They can live up to twenty-five years.
