Snakes and serpents have long been thought to represent a battle between good and evil.
Reptiles and Amphibians appear in superstitious Biblical tales and other cultural myths and legends throughout history. Because snakes shed their skin through the process of moulting, they are often considered to be symbols of rebirth, transformation, immortality, and healing. Some of the oldest rituals and fables are about snakes.
Fanciful tales of Frogs and toads fill the pages of folklore and fairy tales in many cultures. The earliest frog story is attributed to Aesop, a slave of Phrygian origin who lived on Samos, a Greek island in the eastern Aegean Sea. Aesop is said to have authored many fables, including "The Frogs Who Desired a King" a political allegory and one of the 38 Aesop's fables.
Large Crocodiles, Alligators and Caimans are very dangerous to humans and kill hundreds of people every year in south-east Asia and Africa. Because the crocodile is so dangerous to humans who worked or traveled on the Nile, ancient Egyptians prayed to Sobek, for protection from being attacked by crocodiles. The crocodile god Sobek appears in Egyptian art works depicted as both an ordinary crocodile, and as a man with the head of a crocodile. The Sobek is usually depicted holding an ankh to represent his ability to undo evil and cure illness.
