Cheyletiella blakei Mite - Small Cat pest view under a microscope

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.

Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.

$Haliotis kamtschatkana, northern abalone or pinto abalone, is a species of large sea snail, a marine gastropod mollusc in the family Haliotidae, the abalones. It has been listed as \$

Microscopic photo of a thin section of calcareous tufa of Holocene age.

Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens. Depth of focus is extremely shallow (just a few microns). Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

Photomicrograph: Fungal colony, skin scraping for fungus test

Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.

Rare Scorpion (Arachnida) inclusion in Burmese amber, Myanmar, Cenomian, Upper Cretaceous, approximately 100 million years ago, age of dinosaurs. Image taken with extreme macro and focus stacking technique.

Licmophora sp. is a genus of benthic diatom. It is an epiphyte, which means it must perch on another organism or object for structural stability
