Description

This diatom, genus Gyrosigma, was found towards the middle of the Colorado River, on top of a shoal. The water was no more than 6 inches deep, and was moving at a moderate rate.

Gyrosigma species are symmetrical braphids that are sigmoid in shape, or shaped like an S-curve. Their striae are punctate, meaning they have tiny pores. The central area is circular or elliptical in shape ("Gyrosigma." Diatoms of the United States. University of Colorado, 2009. Web. 17 Nov. 2016.).

Description from Wikipedia

Diatoms are a major group of algae, and are among the most common types of phytoplankton. Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons (e.g. Fragilaria), fans (e.g. Meridion), zigzags (e.g. Tabellaria), or stars (e.g. Asterionella). Diatoms are producers within the food chain. A unique feature of diatom cells is that they are enclosed within a cell wall made of silica (hydrated silicon dioxide) called a frustule....
