Jellyfish use them for protection as well as for the capture of a prey. Cnidocytes are basically small compartments which house mini-needle like stingers. The stinger lies coiled under high osmotic pressure. Now, when there is a trigger due to an external force, the lid of the stinging cell pops open and sea water rushes in. This forces the mini-needle like stinger to shoot out, penetrate and finally inject venom into the victim. This discharge can occur in less than one millionth of a second. This is how a Jellyfish Stings.
