Keesingia gigas is a large species of box jellyfish discovered in the coastal waters of Western Australia and scientifically described in 2014. It belongs to the class Cubozoa and is notable for its unusually large bell size, which can reach up to 50 centimeters in length. Uniquely among jellyfish, specimens of this species have been observed swimming without any visible tentacles. It is related to the deadly Irukandji jellyfish, though its specific ecology and toxicity remain subjects of scientific study.
