Calcareous phytoplankton. Coloured scanning electron micrograph (SEM) of the external mineralised structure (coccosphere) of a small marine algal organism (phytoplankton) called a coccolithophore. Coccospheres are made up of coccoliths, which are individual plates of calcite crystals. Magnification: x3000 when printed 10 centimetres wide.
