What is the biggest spider in the world?

Spiders can be super tiny and really hard to see.

Or they can be as big as a dinner plate.

Really!

Here are two big spiders you should know about.

The Goliath bird eater is often called the world's biggest spider.

It can be 11in across from leg tip to leg tip.

That's as big as the long side of a standard sheet of paper.

Its body alone is about five inches wide, and Goliath bird eaters can weigh an impressive six ounces.

These giant tarantulas are found in South America, and contrary to their name they don't actually eat birds, even if they're big enough to.

There's another spider with an even bigger span.

The giant huntsman spider can be a foot across the size of a dinner plate.

These spiders are found in Australia and actually weigh a little less than the Goliath bird eater, but have longer legs.

While both of these spiders grow to an impressive size and do have venom, their bites aren't deadly, just painful.

These spiders are more likely to run away from humans than bite them, and with good reason.

Some humans actually eat Goliath bird spiders, not the other way around.
