Regular Cone Shell, Conus regularis: The Regular Cone Shell is an ivory white shell profusely marked with spiral rows of brown spots and axial streaks of purplish brown.
The species is somewhat variable but the one found in the greater Los Cabos area has a high spire and a white aperture.
They reach a maximum length of 5.9 cm (2.3 inches) and are found intertidally and offshore from depths of 15 feet to 270 feet.
They are found from Magdalena Bay south along the west coast of Baja, throughout the Sea of Cortez and south along the coast of the mainland to Guatemala.
The Regular Cone Shell is a member of the Conus Family which has approximately 500 known members and includes medium to large-sized, sophisticated predatory sea snails which are commonly referred to as cone snails, cone shells or cones.
They are known from the Eocene period (56 million years ago). Cone shells and specifically Conus regularis have been found in an archaeological dig in Arizona in the late 1800s. The shells were used as rattles in ceremonies of Indian tribes, jewelry and were also found tied to garments of the deceased. Cone shells have also been used as a currency. They have been used by various cultures to signify status. They also provide a food substance to some cultures today and are of increasing interest scientifically due to biomedical potential of their toxic venoms.
