Sinum is a genus of predatory sea snails, marine gastropod mollusks in the family Naticidae, the moon snails.[1] Most naticids have shells that are globular, but the shell of species in the genus Sinum is flattened to some extent, some being so flattened that they are ear-shaped.


This marine species is cosmopolitan.


Species within the genus Sinum include:
