The azhdaha, azhdahak, ezhdeha or azhdar (اژدر) is a mythical creature in Iranian mythology, roughly equivalent to the dragon. In Persian literature, they are depicted as gigantic, winged serpents that live in the air, in the sea, or on the earth. According to tradition, azhdaha have huge bodies, fierce faces, bright eyes, and wide mouths with many teeth. The azhdaha are principally discussed in Sad dar-e nathr and sad dar-e Bondahesh, Shahnameh and Garshaspnameh.
