Himba women wear only 2 types of cone shell : marbled cone or leopard cone . The patterning on these two cones are almost opposites. The marbled cone ( conus marmoreous ) is about the most striking of all shells, black in colour covered with uniformly sized white tents. It is predatory, living on other molluscs and inhabits the coral reefs. Leopard cone ( conus leopardus ) is uniformly banded, with evenly sized and spaced black spots. These snails are highly venomous.
The Marbled Cone Snail is found in the warm and temperate waters of western pacific ocean, Bay of Bengal and Indian Ocean. It is the most venomous of all types of Cone Snail and can kill a grown man with the amount of venom it has in it.
