History of World Jellyfish Day

Since 2014, the third of November has served as the date for World Jellyfish Day. It’s springtime in the southern hemisphere, and this is the time of year when jellyfish start to migrate to the northern hemisphere’s coastlines.

Significance of World Jellyfish Day

The jellyfish has a significant impact on the biomass, spatiotemporal dynamics, and community structure of the global marine plankton ecosystems. They provide food for us, house young fish in their tentacles, and are being studied for potential medical applications due to the green fluorescent protein that causes their bioluminescence, toxins, and tissues.

Jellyfish are often seen as pests or nuisances, but they are actually important members of the marine ecosystem. They eat plankton, which are tiny organisms that float in the water. Plankton is the base of the marine food chain, so jellyfish help to support all other marine life.
