Scanning electron microscope image of valve. The organism is tentatively identified as C. radiatus. Sample taken from the water column off Martha's Vineyard, Massachusetts. Image by Charley O'Kelly and Shauna Murray.

Scanning electron micrograph showing detail of the frustule of this diatom. The larger depressions are called areolae, and perforated region is called the cribrum, within which each perforation is referred to as a cribellum. The same term probably also refers to the perforations in the margins of the areolae. The species is probably C. radiatus. Sample from the water column off Martha's Vineyard. Images by Charley O'Kelly and Shauna Murray.
