These 12 Biggest Spiders are What Nightmares are Made of

Goliath Bird-Eating Tarantula

With its 1-foot body length and 1-inch long fangs, you will definitely run for your life should you see one. It may not eat birds, but it can do so considering its body size. It also has a heavier body mass. This means you just can’t kick it out of your way if you happen to stumble on it. It has tiny hairs that can cause allergies and bites that can be severely painful. If you hear a hissing sound, don’t just think of a snake. It could be this poisonous spider.
