Does anyone have any interesting serpent myths?

The person above mine really laid out a lot of information, but there is the Naga serpent of Creation from Angkor Wat, very interesting! Tiamat, comoslogical serpent that all creation came from. Ureaus from Egyptian mythology, represents a person who is twice born. Ananta, the serpent Shesha, from India, & Indra slayed a Vritra, which released the fertilizing waters it had enclosed; & the earthquake snake, Vasuki, that churned the sea of creation. Quetzacoatl, Aztec version!
