The calcarinidae, which measure only a millimetre in size and have shells composed of calcium carbonate, mainly occur in the Western Pacific. They are characterized by radiating appendices of the shell, which give them a starlike appearance. The following calcarinidae are presented: Baculogypsina sphaerulata, Calcarina calcar, Calcarina defrancii, Calcarina gaudichaudii, Calcarina hispida. The presentation includes quick-motion sequences.
