box jelly

Deadly transparent stinger

A box jelly is a jellyfish with a cube-shaped bell, found in tropical and subtropical waters.

Some species, particularly those in Australian waters, carry extremely potent venom that can be fatal to humans within minutes.

The name distinguishes them from the rounded bells of typical jellyfish: We saw warning signs about box jellies at the beach.
