Monetaria caputdraconis, common name the "dragon's-head cowry", is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries.
The common name of this species comes from its Latin name caputdraconis, meaning "the head of the dragon".
The shell reaches about 15–40 millimetres (0.59–1.57 in) in length. It is pyriform with rather long teeth. The basic color of the shell is uniformly brown on its edge, with many yellowish small spots on the top of the dorsum.
This endemic species is found in the sea along Easter Island and Sala y Gomez Island, where it replaces the similar Monetaria caputserpentis . It is mainly encountered under coral rocks in the intertidal reef.

Shell money is a medium of exchange similar to coin money and other forms of commodity money, and was once commonly used in many parts of the world. Shell money usually consisted of whole or partial sea shells, often worked into beads or otherwise shaped. The use of shells in trade began as direct commodity exchange, the shells having use-value as body ornamentation. The distinction between beads as commodities and beads as money has been the subject of debate among economic anthropologists.
