Even though they don’t have wings, spiders can fly for hundreds of miles (across entire oceans) on long strands of silk using Earth’s electric fields; it’s called “ballooning.” Spiders have been found two-and-a-half miles up in the air, and 1,000 miles out to sea.

Spiders don’t have muscles in their legs. They extend them using a system of hydraulics powered by their blood pressure. When they die, spiders’ legs curl up because the blood pressure is gone.

Spiders have a tiny “paw” at the end of their legs. It’s called a tarsus.

The Wrap-around Spider, indigenous to Australia, can flatten and wrap its body around tree limbs like a camouflage.

Male spiders give female spiders gifts of prey wrapped in silk to increase mating success. Wrapping the gift in silk prevents the female from stealing it without copulating and sometimes conceals that the gift is just random trash.

Mazda had to recall 52k cars due to a species of spider loving the smell of gasoline so much it chose to build its web in the cars emission systems.

The affected model, the Mazda6, has two pipes coming out from its gas tank, which is extremely rare and means that the smell of gasoline is strong enough to draw the spider in but not strong enough to kill it.

To avoid being eaten by the female, some male spiders will often tie her up before mating.

When you kill a spider, you make the spider population in your house smarter and sneakier by taking a stupid spider out of the gene pool.
