C. geographus has a broad, thin shell, cylindrically inflated. Geography cones grow to about 10 to 15 cm (4 to 6 in) in length. The size of an adult shell varies between 43 and 166 mm (1.7 and 6.5 in). The ground color of the shell is pink or violaceous white, occasionally reddish.
The shells of cone snails vary in size and are conical in shape. The shell is whorled in the form of an inverted cone, with the anterior end being narrower. The protruding parts of the top of the whorls, that form the spire, are in the shape of another more flattened cone. The aperture is elongated and narrow with the sharp operculum being very ...
Some previous classifications grouped the cone snails in a subfamily, Coninae. As of March 2015 Conidae contained over 800 recognized species, varying widely in size from lengths of 1.3 cm to 21.6 cm. Working in 18th-century Europe, Carl Linnaeus knew of only 30 species that are still considered valid.
The thick shell of species in the genus Conus sensu stricto, is obconic, with the whorls enrolled upon themselves. The spire is short, smooth or tuberculated. The narrow aperture is elongated with parallel margins and is truncated at the base. The operculum is very small relative to the size of the shell.
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 Registry of World Record Size Shells is a conchological work listing the largest (and in some cases smallest) verified shell specimens of various marine molluscan taxa.A successor to the earlier World Size Records of Robert J. L. Wagner and R. Tucker Abbott, it has been published on a semi-regular basis since 1997, changing ownership and publisher a number of times.
The size of an adult shell varies between 65 mm and 163 mm. The shell is rather narrow and has an elevated spire. The color of the shell is chocolate-brown, covered by elevated close revolving lines of darker color. The surface is irregularly overlaid by subtriangular white spots, some of which are very large.
Conus litoglyphus, common name the lithograph cone, is a species of predatory sea snail, a marine gastropod mollusk, more popularly known as a cone snail, cone shell or cone. [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 ...
