Spiders don’t have wings, but they can fly across entire oceans on long strands of silk. For more than a century, scientists thought it was the wind that carried them, but a new study shows the Earth’s electric field can propel these flying arachnids too.
how can they survive?
If they aren’t doing anything, they dont need any energy.
Also, probably not all of them do.
Most spiders can go a long time without eating, and most are too small to be killed from falling to the ground
