A Shankha (conch shell) has religious ritual importance in Hinduism. It is the shell of any suitable sea snail which had a hole made for the performer's embouchure. In Hindu history, the shankha is a sacred emblem of The Hindu preserver god Vishnu. It is still used as a trumpet in Hindu ritual, and in the past was used as a war trumpet. The shankha is praised in Hindu scriptures as a giver of fame, longevity and prosperity, the cleanser of sin and the abode of goddess Lakshmi, who is the goddess of prosperity and consort of Vishnu. The shankha is displayed in Hindu art in association with Vishnu. As a symbol of water, it is associated with female fertility and serpents (Nāgas). The shankha (representing the conch of the presiding deity of Padmanabhaswamy Temple is a part of the state emblem of the Indian state of Kerala. The symbol was derived from the erstwhile emblems of the Indian princely state of Travancore, and the Kingdom of Cochin. The shankha is one of the eight auspicious symbols of Buddhism, the Ashtamangala, and represents the pervasive sound of Buddhism. A powder made from the shell material is used in ayurveda as a treatment for stomach ailments. In the Western world, in the English language, the shell of this species is known as the "divine conch" or the "sacred chank". It may also be simply called a "chank" or conch. The more common form of this shell is known as "right-turning" in a religious context, although scientists would call it "dextral". A very rarely encountered form has reverse coiling which is called "left-turning" in a religious context, but is known as "sinistral" or left-coiling in a scientific context. Characteristics This shell is from a sea snail species Turbinella pyrum in the family Turbinellidae. This species is found living in the Indian Ocean and surrounding seas. The shell is porcelaneous (i.e. the surface of the shell is strong, hard, shiny, and somewhat translucent, like porcelain). The overall shape of the main body of the shell is oblong or conical. In the oblong form, it has a protuberance in the middle, but tapers at each end. The upper portion (the siphonal canal) is corkscrew-shaped, while the lower end (the spire) is twisted and tapering. Its colour is dull, and the surface is hard, brittle and translucent. Like all snail shells, the interior is hollow.
