World Jellyfish Day Cards

An informal global awareness day observed by aquariums, marine scientists, conservation groups and ocean enthusiasts to celebrate jellyfish, highlight their ecological roles and biology, and raise awareness about issues such as jellyfish blooms, climate-change effects on marine ecosystems, and the need for ocean conservation. Activities often include aquarium events, educational outreach, citizen-science projects, and social-media campaigns. The day is not governed by an international body and has grown through community and institutional participation rather than formal designation.
