Conus sanguineus is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails, cone shells or cones.
These snails are predatory and venomous. They are capable of "stinging" humans. Commonly, they are known as cone snails.
The size of the shell varies between 38 mm and 78 mm. The spire is concavely elevated, not coronated. The body whorl is smooth, slightly striate below. It is irregularly marbled with chestnut and white, with equidistant chestnut revolving lines bearing white, granularly elevated spots.
