Scanning electron micrograph of the lumenal surface of the toad bladder shows the boundaries of four polygonal squamous epithelial cells surrounding a mitochondrial-rich cell bearing short globular mi...

Scanning electron micrograph of the epidermal surface of the Pacific coho salmon. Ridge-like folds of the plasmalemma, called microplicae, display a labyrinth pattern across the surface, and a circum...

Scanning electron micrograph of the epidermal surface of lamprey larvae. A row of microvilli outline the polygonal borders between cells, while short microvilli cover the external surface in a reticu...

The final stages of cell division is captured in the scanning electron micrograph. Two daughter cells are still interconnected by slender strands of membrane (white arrow at center of image). Lamell...

This image shows two different types of white blood cells from a mouse which are essential for mammalian immune response to protect from infection. The larger cell is a macrophage and the smaller two...

Didinium captures Paramecium. Paramecium is almost completely ingested and the proboscis is beginning to reform. This micrograph was taken in 1968 by G. Antipa on a Cambridge Mark IIA operating at 20k...

Didinium captures Paramecium. After reeling in the prey with cyclosis tugging at the attached toxicysts the proboscis opens to engage the Paramecium. This micrograph was taken in 1968 by G. Antipa on ...

Didinium captures Paramecium. At midingestion and showing metachronous waves of cilia within the two characteristic ciliary girdles of Didinium nasutum. This micrograph was taken in 1968 by G. Antipa ...

Apical oral view of Didinium. Showing the proboscis containing extrusive organelles to demobilize and eventually engulph it's prey. Metachronous waves of cilia in the anterior girdle of the two charac...
