WHY does a jellyfish sting and using what?

On the edges of the jellyfish’s body lie tentacles with cells containing capsules of venom that cause burns.

The tiny stingers paralyze small prey. Jellyfish stalk fish and other sea creatures, and humans frequently fall prey to the toxin as well.

Even a jellyfish newly washed ashore is hazardous as long as its tentacles are wet.

There are several species of jellyfish capable of killing humans with their venom, such as the sea wasp, found in the coastal waters of Australia. The same one depicted here.
