Mainly molluscs like bivalves (clams) and gastropods (sea snails). Large crustacea like lobsters and crabs also have calcite in their exoskeletons. And of course we must not forget the corals, some bryozoans, calcerous sponges, and the echinoids.
Many tubeworms (Annelida) also build calcite homes, and even some protozoa such as the Foraminifera. These are responsible for vast limestone and chalk deposits in the past.
Even some plants use calcite, particularly the coralline red algae and a peculiar advanced algal plant, Chara sp. has calcite as a stiffener in its stems
