The bodies of all box jellyfish in their adult, or free-swimming medusa, form resemble a box-shaped bell, with clusters of tentacles trailing from each corner of the bell. Depending upon the species, the bell's diameter can range in size from 1-30 cm (0.4-11.8 inches), and the tentacles can extend up to 3 metres (9.8 feet) in length. Cubozoa (Box jellies) Phylum Cnidaria. Class Cubozoa. Number of families 2. Thumbnail description Gelatinous animals that possess image-forming eyes and complex behavior, including internal fertilization in at least one species; often known as "killer box jellies," although only one of the seven genera (Chironex, in the family Chirodropidae) is potentially lethal to humans The box jellyfish is an invertebrate in the class Cubozoa.
