Did you know that there are an estimated 21 quadrillion (21,000,000,000,000,000) spiders alive in the world today?

On average, there are about 131 spiders per square meter of land across the globe. In highly favorable, lush environments, that number can skyrocket to over 1,000 spiders per square meter.

For every single human on Earth, there are roughly 2.8 million spiders.

Biologists have officially mapped and named over 53,000 unique spider species, though they estimate at least another 50,000 species.

Does this trigger those of you who are arachnophobic?
