How have jellyfish flourished for over half a billion years?
In short: From creatures larger than blue whales to microscopic specks, jellyfish have occupied the oceans for at least 500 million years. This video explores the diverse biological secrets that allow these ancient organisms to thrive.
Jellyfish exhibit an extraordinary range of scales, with some species exceeding the length of a blue whale while others are barely larger than a grain of sand. Beyond their size, they possess remarkable biological capabilities, such as highly potent venoms and unique biological mechanisms that have inspired significant breakthroughs in modern scientific research. Their ongoing prosperity after living in the sea for over 500 million years indicates a very successful way of surviving.
