Diatom

Microscopic single-celled alga enclosed in a rigid, glasslike silica frustule composed of two fitted halves. The frustule is translucent with crisp edges and etched geometric patterning, including fine pores, perforations, and ridges. The cell shows a golden-brown interior and overall delicate glassy appearance. It may be depicted either as a circular disk with radial symmetry and radial markings, or as an oval, elongated oval, pill-, capsule-, or boat-shaped form with bilateral symmetry.
