Euglypha
This is a sample of Euglypha from a municiple sludge. With this type of illumination the overlapping silica scales can be detected by their optical effects. Near the center of the body are a few scales in focus. The other scales are delimited by the light and dark patterns they create.

Characteristic Features:
This small species of Euglypha has a body composed of overlapping silica plates. The scales are about 5 to 7 micrometers in diameter and only a few tenths of a micrometer in thickness. The opening at the bottom of the cast is jagged as a result of the terminal scales projecting along the opening.Associated Particles:
