Himba women ( a nomadic tribe in southern Angola ) 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 striking : 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.
