Jellyfish tentacles are still able to sting after separation from the creature's body or even after it is dead. Stings from jellyfish tentacles that are separated from the body typically occur because of ocean tides that scatter them in the water. Jellyfish tentacles contain specialized cells that are activated by touch to release the venomous stingers. Even if a jellyfish is dead, its tentacles are able to be activated and sting prey, emitting toxins that can cause pain or severe allergic reactions — or even death in humans, in rare cases.
