In some cultures, the Rainbow Serpent is male; in others, female; in yet others, the gender is ambiguous or the Rainbow Serpent is hermaphroditic or bisexual, thus an androgynous entity. Some commentators have suggested that the Rainbow Serpent is a phallic symbol, which fits its connection with fertility myths and rituals. When the Serpent is characterized as female or bisexual, it is sometimes depicted with breasts. Other times, the Serpent has no particular gender. The Serpent has also been known to appear as a scorpion or another animal or creature. In some stories, the Serpent is associated with a bat, sometimes called a "flying fox" in Australian English, engaged in a rivalry over a woman. Some scholars have identified other creatures, such as a bird, crocodile, dingo, or lizard, as taking the role of the Serpent in stories. In all cases, these animals are also associated with water. The Rainbow Serpent has also been identified with the bunyip, a fearful, water-hole dwelling creature in Australian mythology.
