Conus obscurus, common name the obscure cone, is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.[2]

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.

Description

The size of an adult shell varies between 20 mm and 44 mm. This small to medium-sized shell is shaped like a small Conus geographus but with smaller coronations on the shoulder. The shell is subcylindrical, violaceous, with chestnut blotches, forming two interrupted bands, and faint lines of minute chestnut and white articulations. The aperture is very wide anteriorly caused by a concave lower half of the columella. [3]

Distribution

This species occurs in the Indian Ocean along Aldabra, the Mascarene Basin and Tanzania; in the Pacific Ocean to Hawaii and French Polynesia.
