''Conus geographus'', popularly called the geography cone or the geographer cone, is a species of predatory cone snail. It lives in reefs of the tropical Indo-Pacific, and hunts small fish. Although all cone snails hunt and kill prey using venom, the venom of this species is potent enough to kill humans.〔WoRMS (2010). Conus geographus Linnaeus, 1758. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=215499 on 2011-07-24〕 Specimens should be handled with extreme caution. The variety ''Conus geographus'' var. ''rosea'' G. B. Sowerby I, 1833 is a synonym of Conus eldredi Morrison, 1955 ==Shell description== ''C. geographus'' has a broad, thin shell, cylindrically inflated. Geography cones grow to about to in length. The size of an adult shell varies between 43 mm and 166 mm. The ground color of the shell is pink or violaceous white, occasionally reddish. It has a mottled appearance, clouded and coarsely reticulated with chestnut or chocolate, usually forming two very irregular bands. This intricately brown-and-white pattern is highly prized by shell collectors.〔(【引用サイトリンク】title=Geographic Cone Snail Profile )〕 The geography cone has a wide, violaceous white or pink aperture and numerous shoulder ridges or spines.〔 The shell is covered with thread-like revolving striae, usually nearly obsolete except at the base. The flattened spire is striated and coronated.〔〔George Washington Tryon, Manual of Conchology, vol. VI p. 88; 1879〕 In comparison with other species, the shell has a noticeably wider and convex mid-body, with a flattened spire. Its walls are also noticeably thinner and lighter compared to other cone shells of similar length and size.
