One Gif to Rule Them All: From Amphipod to Diatom to Bacterium. Captured in this amazing image is an electron microscope scan that zooms in on a tiny bacterium perched upon a diatom, lodged near the leg of an amphipod (a type of crustacean). Watch the scale at bottom right, go all the way from a millimeter, through the range of micrometers, down to 500 nanometers!

I was reminded of the verse by Jonathan Swift (1733):
"So nat'ralists observe, a flea
Hath smaller fleas that on him prey,
And these have smaller fleas that bite 'em,
And so proceed ad infinitum ."
