My Original Idea

What if that jellyfish couldn't sting you? Would we still have jellyfish today or would they be gone! Jellyfish usually catch their prey with there tentacles and if they didn't have tentacles to sting with and to catch their prey with they wouldn't be able to eat and maybe not even survive without their tentacles. They would have no food and maybe even be food to other animals if they couldn't sting. People might even eat them if they didn't sting. If they didn't sting they would get washed up on shore and people would kill them because they wouldn't be able to defend themselves. I think without their tentacles they would die.
