This image illustrates the frustule (silica cell wall) of a warm-water marine diatom, Podocystis spathulata. Diatoms are aquatic, single-celled algae which possess a hard shell. The shapes vary but al...

An anoptral contrast micrograph of a planktonic freshwater rotifer. The rotifer are microscopic but complex animals (mostly less than 1mm long) found in wet habitats. They are important members of the...

Colorized light micrograph of Aggregatibacter actinomycetemcomitans colonies. A. actinomycetemcomitans is a Gram-negative bacteria commonly found to cause infections of the oral cavity and often isola...
