Azhdaha, Azhdahak, Ezhdeha (Persian: اژدها) or Azhdar (اژدر) is a mythical creature in Iranian mythology, roughly equivalent to the dragon.
[1] According to tradition, they have a huge body, a fierce face, their mouths are wide with many teeth, and their eyes are bright.
He also wrote that "because of their harassment to other creatures, God eventually will throw them into the sea and in there, their body will continue to grow, such that their length becomes more than 10,000 Gazes.
Completed in 1339–1340, the author and historian, Hamd Allah Mustaufi Qazvini, describes the azhdaha as being terrible in appearance, with flaming eyes, a wide mouth, and a body of enormous length.
Eventually it grew so much that it caused damage in the sea, and after it was killed, its body was cast up on the shore to provide food for the inhabitants of the Land of Gog and Magog.
