Cassis madagascariensis, common name the queen helmet, is a marine gastropod mollusc in the family Cassidae, the helmet shells and bonnet shells.[1]
Distribution
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
The maximum recorded shell length is 409 mm.[2]
Habitat
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
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.
