Morbakka virulenta is a cubozoan box jellyfish (family Chiropsalmidae) found in coastal waters of the Indo-Pacific including Japan and Southeast Asia, possessing multiple tentacles per corner of the cube-shaped bell bearing thousands of nematocysts capable of delivering painful and potentially dangerous stings. Its venom contains pore-forming toxins that can cause cardiovascular and hemolytic effects, and stings in humans may require medical attention. The complex, camera-type eyes of cubozoans like Morbakka are a subject of active research into the evolution of sophisticated visual systems in non-vertebrates. Genomic data have been generated for this species and are available in public databases, enabling comparative studies of cnidarian evolution and ecology.
