“Human #follicular #mites: #ectoparasites becoming #symbionts” (Smith et al. 2022)

Do you think about the mites that live in your #face #follicles and come out at #night while you #sleep? Maybe you should!

🧬 They’ve #evolved a tiny #genome.

💪🏻 Each leg segment is powered by only one #muscle cell.

😴 They follow your sleep cycles by responding to your #melatonin.

🧫 Lowest number of cells of any #arthropod.

If you find this intriguingly #weird, this paper is for you! 🤯
