There is a spider somewhere on your body. Spiders are incredibly common any place that small invertebrates exist. Do you remember the last time you saw, felt, or heard a small invertebrate? It was in the past day, was it not? Those invertebrates have predators. Have you encountered a spiderweb recently? If so, where is the spider now? If not, what sort of spider is so sneaky it doesn’t need a web?
I’ll tell you. The spider that is crawling just slightly too lightly for your skin to feel it. That is the spider. You have a spider on you.
Spiders also are born in large batches of eggs. That spider is not alone.
