Unlike other zodiac signs with one symbol, Scorpio is represented by three creatures representing evolutionary stages: the Scorpion (base instincts, defense), the Eagle (rising above, perspective), and the Phoenix (transformation, rebirth).
These three symbols represent Scorpio's journey from reactive survival mode to higher consciousness and eventual transformation. Ancient astrologers recognized that Scorpio natives could operate at different vibrational levels.
Some modern astrologers add a fourth symbol - the Dove - representing ultimate peace and spiritual transcendence after transformation.
