The Joy Of Jellyfish

Jellyfish are undeniably majestic, yet mysterious creatures of the ocean. Their natural bioluminescence—or ability to emit their own light—combined with their graceful, mesmerizing swim gives the jellyfish its signature look. But the species' specialities don't stop there: Jellyfish can self-clone, eat peanut butter and display a distinctive shape that researchers use to learn more about underwater propulsion. What's more—despite the jellyfish's lack of a brain, some are even known to live forever. The jellyfish generally goes through two major life phases—the stationary polyp stage and then mobile medusa phase—before reaching the end of its lifespan. However, during times of stress the Turritopsis nutricula species has the ability to transition between life stages, earning its immortal reputation. That's a pretty incredible feat for not having a brain.

So if some jellyfish are immortal, how far back does the species date? How has their gentle, flowing movements influenced the way we look at technology? Check out this playlist to learn more about the amazing ways in which jellyfish contribute to society: everything from modern medicine to protecting other vital species with stinging tentacles.
