Does anyone know what kind of microbe this is?

Sidenote: for a second I read "emoji" as plural, and envisioned a handful of different microbes (e-coli, amoeba, cyanobacteria, etc). I got excited that finally, 400 years after microbes were revealed to us, USB microscopes had so democratized the technology that the Unicode Consortium saw fit to familiarize us with our tiny fellow inhabitants of Earth, our distant cousins on the tree of life.

Hey, I can dream can't I? ;)
