What you're going to see is an animated gif made by James Tyrwhitt-Drake using a scanning electronic microscope at the University of Victoria's Advanced Microscopy Facility. At the final stop of this zoom, which spans multiple orders of magnitude, is a little bacterium.
That bacterium is resting on a diatom (like the one pictured above), a class of algae that are known for their silica shells. The diatom is, in turn, sitting on an amphipod, a type of shell-less crustacean.
