tiger cowrie shell (Cypraea tigris). Tiger cowries are a species of large sea snail known for their distinctive, glossy, egg-shaped shells. Appearance: The shell is typically white or pale with numerous dark brown or black spots, resembling a tiger's coat. The surface is naturally shiny, which is why cowries are sometimes called "porcelain shells". Habitat: They are found in the coastal waters of the Indian and Pacific oceans. Mantle: The snail has a fleshy mantle that it can extend to cover the shell, which keeps the shell clean and shiny.
