This scanning electron microscope (SEM) image shows a Eutardigrade (Macrobiotus spp.). Pictures from a SEM only show surface details. Specimens are prepared for SEM in a multi-step process that involves completely drying the animal and then coating it in gold before images can be taken. In the Microscopy Lab at Brigham Young University in Provo, Utah.
