The biggest spiders in the whole world?

Answer 1

Recently the 'World's Largest Spider Ever Fossil" was debunked as being a crab. So as far as I know your best bet is a Camel spider. but... before you count that, Camel Spiders aren't technically spiders.

-The Camel Spider is also not as large as people think. Much larger is the Goliath Bird Eating Spider- http://en.wikipedia.org/wiki/Goliath_Bird_Eating_Spider actually the largest spiders are the huntsman spiders of south East Asia. With a larger leg span than the goliath spider of south america.

Just a short note to say that when the fossil of the Megarachne servinei was found in 1980, it was indeed considered by the paleontologists as the 'World's Largest Spider Ever", with a leg span of half a metre.

However, in 2005, a second more complete fossil was found in Argentina, and after comparative study with the holotype, paleontologist Dr. Paul Delden concluded that Megarachne servinei was not a spider, but was in fact a sea scorpion, an eurypterid from the Pennsylvanian epoch of the Carboniferous period.

A: The Goliath Birdeater!

Watch out - Here it comes!

Native to the rain forest regions of northern South America, these spiders have up to a 30 centimeter (12 in) long leg span when fully extended and can weigh over 120 grams. Wild goliath birdeaters are a deep burrowing species, found commonly in marshy or swampy areas. Goliath birdeaters usually live in burrows in the ground that they have either dug themselves or have been previously abandoned by rodents or other similar creatures.
