Located on their tentacles, jellyfish's stinging cells are called cnidocytes. They are small compartments that house a mini needle-like stinger. When an outside force triggers a stinger, the cell opens, letting ocean water rush in. This causes the stinger to shoot out into what triggered the action; once it’s there, venom is released.
