Dead Jellyfish Still Sting: Doctor Explains Deadly Beach Danger

Jellyfish Stings: A Deadly Danger Lurks Even After Death A recent video highlights a serious danger often overlooked by beachgoers: the potentially fatal sting of a dead jellyfish. The video, featuring Dr. Myro Figura, MD, explains that microscopic structures called nematocysts, which deliver venom, can remain active for days after the jellyfish dies. "Even a dead jellyfish can sting you, and I mean dead for days," Dr. Figura explains in the video. This means even washed-up jellyfish pose a significant threat. The video shows a man experiencing a painful sting from a jellyfish, illustrating the potential severity of the situation. While most jellyfish stings cause only minor discomfort, certain species, like box jellyfish and Portuguese man o' war, can cause cardiac arrest or respiratory failure, leading to death. Dr. Figura's warning serves as a crucial reminder of the importance of beach safety and awareness of the dangers posed by jellyfish, even those seemingly lifeless on the shore. Always exercise caution near the water and seek immediate medical attention if stung by a jellyfish.
