Below is the link to a great compilation of frightening images from under the microscope.
What do the tiny beings in our world look like when you zoom way WAYYY in? Some are straight up scary looking. Insects, worms, and parasites of all sorts are among the worst. I have known this for a while, given my biology background, but none freaked me out quite like the detailed micrographs and drawings of the heads of marine worms. I did my undergraduate thesis on one such creepy worm and as a result spent a lot of time looking at these pictures – so much time that these freaky-faced worms have invaded my nightmares on more than one occasion. Yes, the mark of a true nerd. Their miniscule, little faces are often adorned with tentacles, bristles, and raptorial jaws for maximum (mini) destruction power! Anyhow, appropriately so, these marine worms occupy at least 3 spots on this lovely list. Check it out!
