Here is a list of mythical creatures beginning with this letter and I am constantly gathering information from each continent and continually updating.
Akupara (Hindu)
The World Turtle (also referred to as the Cosmic Turtle, the World-bearing Turtle, or the Divine Turtle) is a mytheme of a giant turtle (or tortoise) supporting or containing the world. The mytheme, which is similar to that of the World Elephant and World Serpent, occurs in Hindu, Chinese, and Native American mythology. The Lenape myth of the "Great Turtle" was first recorded between 1678 and 1680 by Jasper Danckaerts. The myth is shared by other Northeastern Woodlands tribes, notably the Iroquois.The Lenape myth of the "Great Turtle" was first recorded between 1678 and 1680 by Jasper Danckaerts.
Hindu mythology has various account of World Tortoises, besides a World Serpent (Shesha), Kurmaraja and world-elephants.
The most widespread name given to the tortoise is Kurma or Kurmaraja. The Shatapatha Brahmana identifies the earth as its lower shell, the atmosphere as its body and the vault of heaven as its upper shell.
