Star sand foraminifera shell, light micrograph
Bildnummer 13620282
| Light micrograph of a shell (test) of a Calcarina sp. foraminifera, or sand star. The test was mounted in embedding media and ground down to the equatorial plane of the test. Here you can see the spiralled huge chambers of the calcarina test which inhabit endosymbiotic algae in the living foraminifera. Foraminifera are marine single-celled protozoa that construct and inhabit shells composed of several chambers. These are usually penetrated by pores through which the cellular content is extruded. The shells form an important component of chalk. In past geological ages, foraminifera were so numerous that their shells, largely composed of calcium carbonate, have formed immense fossil deposits, seen today as limestone.
