World Jellyfish Day 2025

World Jellyfish Day is celebrated every year on November 3 to raise awareness about jellyfish and their ecological importance in marine ecosystems. Established by marine biologists in 2014, the day honors these fascinating creatures that have existed for millions of years long before humans. Jellyfish play a vital role in maintaining ocean balance and are known for their unique traits, such as glowing in the dark and surviving without a brain or heart. The day encourages people to explore marine life, visit aquariums, and support ocean conservation efforts worldwide.
