Yes, jellyfish can be killed, although the methods may be more involved than with typical animals.
According to one perspective, a jellyfish isn't a single animal but a colony of microorganisms. Therefore, simply cutting it up won't kill it; the pieces will remain alive and potentially grow. The suggested method for effectively killing a jellyfish involves:
- Removing it from the water.
- Allowing it to dry out on the beach.
- Dousing it in gasoline.
- Setting it on fire.
While this method is extreme, it highlights the resilient nature of jellyfish due to their unique biological structure.
