Once you’ve picked yourself up off the floor in amazement, you’ll probably want to know exactly what you’re looking at in this image.

At the final stop in this gif, which magnifies many times, is a tiny bacterium, which 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.

We think that Reddit user adamwong246 described it best:

There’s a bacterium on a diatom on an amphipod on a frog on a bump on the log in the hole in the bottom of the sea!

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