Conus unifasciatus is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.

[1] Like all species within the genus Conus, these snails are predatory and venomous.

They are capable of "stinging" humans, therefore live ones should be handled carefully or not at all.

Its color is chocolate, with a rather broad yellowish brown band just below the shoulder.
