Jellyfish can’t sting themselves. It works because jellyfish tentacles aren’t inherently venomous. Rather it’s the nematocytes__special cells that line the tentacles. When touched, nematocytes fire off microscopic quills that lodge in a victim and pump in the venom. This weapon comes with a built -in safety switch. Chemoreceptors turn the nematocyte on or off. If the receptors pick up the chemical signature of the jellyfish’s own species, nothing happens.

This kind of kills the joke:
