From years ago: a Demodex human arthropod I recorded with my iPhone through a microscope. They spend their days head down in your hair follicles, drinking oil and eating skin flakes. At night, they emerge to, um, mingle on your face. #NeverReallyAlone #Commensalism

I managed to find a Demodex plushie on eBay. Sadly, no 3D printable models. Demodex are awesome arachnids that live on our skin and have coevolved with us. #NeverReallyAlone.
