At the final stop in this GIF, which is magnified many times, a tiny bacterium, is resting on a diatom, (a class of algae that are known for their silica shells), which is sitting on an amphipod, a type of shell-less crustacean.

The GIF was made by James Tyrwhitt-Drake using a scanning electronic microscope at the University of Victoria’s Advanced Microscopy Facility.
