Arctic Hydromedusa Are Not Like The Mythological Medusa
The mythological Medusa was a beautiful woman who was transformed into a monster with snakes for hair; anyone who looked at Medusa would turn into stone. The story is nice and lends itself to the snake-like tentacles that emerge from the “head” of this would-be jellyfish.
The Arctic Hydromedusa (water medusa) looks a lot like a jellyfish and propels itself through the frigid Arctic waters the way that a regular jellyfish would. What distinguishes this particular creature from a true jellyfish is how they produce its eggs.
