Through an electron microscope, you are observing the foot of a spider.

Examining a spider’s foot under a microscope makes it simple to see how these spooky creatures are able to cling to ceilings and move across walls. The spider can resist gravity and navigate its own webs with the assistance of these claw-like appendages. Because they are adept at distinguishing between sticky and non-stick strands, spiders avoid being entangled in their own webs. Spiders deposit their sticky stings where insects are most likely to get entangled, and they deposit non-sticky strands in areas where they will lie down and wait for their meal.
