Antarctica Is The Only Continent Without Spiders
You think you can escape spiders living in The United States? Wrong! Antarctica is the only continent to have no spiders. Studies have been done that report you are never more than 10 feet away from a spider at all times, although one study showed as close as 3 feet.

Spider’s Silk is Stronger Than Steel
We have all walked through a spiderweb more than once in our lives, but have you ever considered how tough this material really is? Scientists discovered that thousands of smaller strands stick together to form the clingy web. If human size, they even say it could snag a jetliner. Read more about the study here.
The Goliath Spider Is The Largest In The World
The Goliath Birdeater spider is the largest spider in the world and belongs to the Tarantula (Theraphosidae) family. Its fangs can grow up to 1 inch long, and its body can measure up to 11 inches wide. This spider is generally found in Northern South America.

Spiders Only Use Four Of Their Legs To Move
A widely known fact about spiders is that they have eight legs, but did you know when they move they have four legs on the ground, and four in the air the entire time? Tiny special hairs are at the end of spider’s legs which allow them to grip onto surfaces, horizontal or vertical. The fastest spider is believed to be the giant house spider, which can run approximately 34 times its body length every second.
Spiders Have Hydraulic Legs
This may sound ridiculous, but it’s pretty much true! Spider muscles work in weird ways, drawing the legs inward, but their muscles can’t extend the leg outward again. Instead, they create a sort of hydraulic pressure in their midsection, which sends blood (hemolymph) flowing to the legs in order to extend them out again. Almost all other insects with limbs have both flexor and extensor muscles, but not spiders.
