History of World Jellyfish Day
Since 2014, the third of November has been the date of World Jellyfish Day. It’s spring in the southern hemisphere, and this is the time of year when jellyfish begin to migrate towards the shores of the northern hemisphere.
The significance of World Jellyfish Day
Jellyfish have a significant impact on the biomass, spatio-temporal dynamics and community structure of global marine planktonic ecosystems. They provide us with food, hold young fish in their tentacles, and are studied for potential medical use because of the green fluorescent protein that causes their bioluminescence, toxins, and tissues.
Jellyfish are often viewed as pests or nuisances, but they are actually important members of the marine ecosystem. They eat plankton, tiny organisms that float in the water. Plankton is the base of the marine food chain, so jellyfish help sustain all other marine life.
World Jellyfish Day is a significant event that helps raise awareness of jellyfish and their importance in the marine ecosystem. It is also an opportunity to educate the public about the threats jellyfish face and to celebrate their beauty and diversity.
