serpent

A serpent is a snake. If you keep a serpent as a pet, you may have to get used to feeding it live mice.

While you're probably more likely to use the word snake for this slithery reptile, serpent tends to be the word that shows up in folk tales and mythology. Serpents have represented qualities ranging from evil to fertility to poison throughout history, and even today the symbol of medicine is a staff entwined by a serpent. The Latin root is serpentem, "creeping thing," from serpere, "to creep."
