Sinum is a genus of predatory sea snails, marine gastropod mollusks in the subfamily Sininae of 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.
