A 2004 report in the journal Nature attributed about 30 human deaths to cone snails. Cone snails possess a harpoonlike tooth capable of injecting a potent neurotoxin that can be dangerous to humans. They hide under coral shelves, in the sand, or under piles of debris. [3] C. geographus has the most toxic sting known among Conus species and there are reports for about three dozen human fatalities in 300 years. Many species have colorful patterning on the shell surface. Also an aquatic biome consisting of the ocean bottom below the pelagic and coastal zones.
