| Microscopic images of foraminifera, a group of single-celled protists. The specimens appear to be either agglutinated, constructed from gathered sediment particles, or calcareous, composed of calcium carbonate. They are observed under a microscope, with a typical scale bar of approximately 100 µm. Foraminifera are characterized by their shells, known as tests, which occur in a wide range of shapes and structural compositions. |
