Distribution edit
This species occurs in the tropical Western Atlantic, the Gulf of Mexico and the Caribbean Sea. The specific name "madagascarensis" literally means "of Madagascar", but this was a misunderstanding of the type locality by the original author.
Description edit
Habitat edit
United States Virgin Islands, St. John. Emperor/Queen Helmet Snails frequently observed (photographed) in depths as shallow as two feet.[3] This contradicts the previously reported minimum depth of 3 m.[2] The maximum recorded depth is 183 m.[2]
Human uses edit
Shells of Cassis madagascariensis are used in jewellery to make cameos. In the Maldives the shell is boiled and the boiled water of the shell is used as a traditional remedy for Flu and fever like symptoms.
