Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.

Microscopic image of the operculum of a shrimp with possible disease. Research. Study. Laboratory. Aquaculture. Findings of disease in shrimp.
Aspergillus fumigatus is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. This pathogen primarily causes invasive infection in the lung.
Lepocinclis acus or euglena acus, a single cell flagellate eukaryote under the microscope
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Diatoms, algae under microscopic view, phytoplankton, fossils, silica, golden yellow algae
Microscopic image of ascaris cross section
Alternaria spore was zoom by transmission electron microscope. Alternaria is a genus of ascomycete fungi. Alternaria species are known as major plant pathogens.
Some amoebas like this one form shells. Shell is composed of bits of rock (sand), diatom shells, and other debris. Fresh water. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
