The electron microscope referred to here is a Scanning Electron Microscope (SEM). By scanning a specimen with an electron beam and measuring the emitted electrons, it is possible to observe highly magnified images of surface structures.

This page explores the fascinating forms and highly efficient structures created by nature from a microscopic perspective. I hope these images will help visitors appreciate the depth, beauty, and mysteries of nature, and stimulate an interest in natural science.

Regarding image magnification, a scale bar is shown at the bottom of each photograph. Please use this scale to estimate the actual size of the observed object.
