Shankha (Sanskrit: शंख Śaṇkha, pronounced [ˈɕəŋkʰə]) is a conch shell which is of ritual and religious importance in both Hinduism and Buddhism. The shankha is the shell of a species of large predatory sea snail, Turbinella pyrum, which lives in the Indian Ocean.

In Hinduism, 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.

Shankha's significance is traced to the nomadic times of the animists who used the sound emanating from this unique shell to drive away evil demons of whom they were scared.  The same is still believed in Hinduism.  Over the centuries, the shankha was adopted as one of the divine symbols of Hinduism.

An Undine is a water nymph or water spirit, the elemental of water. They are usually found in forest pools and waterfalls.

In 18th-century Scotland, Undines were also referred to as the wraiths of water. Even then, they were not feared as other wraiths such as the kelpie.
