Orange Beach, Ala. — (OBA) —  National Jellyfish Day is an annual observance that raises public awareness of jellyfish biology, behavior, and their role in marine ecosystems. Jellyfish live in every ocean on Earth and have existed for more than 500 million years. They are among the most recognizable marine animals in Gulf waters. The day highlights the importance of understanding these creatures, especially for Gulf Coast beachgoers.

Tuesday, November 3, 2026, marks the nationwide observance. Each year, several jellyfish species move through the waters off Orange Beach and Gulf Shores. The moon jellyfish is among the most commonly seen along Alabama's Gulf Coast. Cannonball jellyfish and sea nettles also appear seasonally in local waters.

Jellyfish stings are a common concern for swimmers at area beaches, especially during the warmer months. Beachgoers are advised to avoid touching jellyfish, even those washed ashore, because they can still sting. Most stings result in mild to moderate skin irritation.

Orange Beach and Gulf Shores post colored beach flags daily to alert visitors to water and marine-life hazards. A purple flag indicates dangerous marine animals, including jellyfish. Swimmers are encouraged to check the flag conditions before entering the Gulf.

Jellyfish sometimes wash ashore tangled in sargassum seaweed on Alabama Gulf Coast beaches. The brown, floating seaweed can make jellyfish harder for swimmers to spot in shallow water and along the shoreline.

Jellyfish play a significant role in the ocean's food chain. Sea turtles, including loggerheads in the Gulf, feed on jellyfish as a primary food source. Some fish and seabirds also regularly consume jellyfish.

Marine researchers have observed that jellyfish populations can increase in warmer waters. Some scientists link rising jellyfish numbers in parts of the Gulf to changes in ocean temperature. The animals are known to thrive in nutrient-rich coastal waters.

National Jellyfish Day reminds us of the Gulf Coast's rich marine biodiversity and the importance of ocean stewardship. Beachgoers are encouraged to observe jellyfish from a safe distance.
