Why does Medusa protrude her tongue?

Medusa, a figure from Greek mythology, is often depicted with her tongue protruding as a symbol of her monstrous nature and as a representation of her rage and defiance. This imagery emphasizes her transformation from a beautiful maiden into a Gorgon, reflecting the curse placed upon her by Athena. The protruding tongue can also signify her deadly power, as her gaze could turn onlookers to stone, and the tongue serves as an extension of her monstrous identity.
