Medusa was once one of three Gorgons, daughters of Phorcys and Ceto, sisters of the Graeae, Echidna, and Ladon – all dreadful and fearsome beasts from ancient Greece. A beautiful mortal, Medusa was the exception in the family, until she incurred the wrath of Athena fearful goddess, either due to her boastfulness or because of an ill-fated love affair with the god Poseidon. Transformed into a vicious monster with snakes for hair, she was killed by Perseus, who afterward used her still potent head as a weapon (gazing at her would turn men into stone), before throwing her into the sea.
Medusa now she roams the oceans for all eternity as a type of Jellyfish, the Medusozoa.
Medusozoans are a type of jellyfish, distinguished from other species by having a medusa stage in their often complex life cycle, a medusa typically being an umbrella-shaped body with stinging tentacles around the edge. The medusa is a free-swimming form; it moves by rhythmic muscular contractions of the bell, providing a slow propulsive action against the water. Touching her tentacles can kill you, and, if you’re in bad luck, gazing at her might still turn you to stone
