Cubes With Eyes and Venom

Box jellyfish have cube-shaped bells and live in warm coastal waters. Unlike many jellyfish that drift, they actively swim and steer, guided by 24 eyes grouped in four clusters. Some of these eyes have lenses and can form images, helping them avoid obstacles.

Chironex fleckeri of northern Australia is among the most venomous animals in the sea, and its sting can be deadly. The tiny Irukandji jellyfish, about a centimeter across, can cause a painful syndrome. Vinegar is used to neutralize unfired stingers before seeking medical help.

During the warmer stinger season, Queensland beaches set up stinger nets around swimming areas, and many swimmers wear full-body stinger suits. Warning signs and vinegar stations help keep beachgoers safe.
