Carukia barnesi, commonly known as the Irukji jellyfish, is a small yet highly venomous jellyfish species found predominantly in the waters of Australia and the Indo-Pacific region. It is notorious for its potent toxin, which can cause Irukji syndrome—a severe and potentially life-threatening condition characterized by intense pain, hypertension, and systemic symptoms. Despite its diminutive size, C. barnesi poses significant health risks to swimmers and divers in affected areas.
