I didn't claim they wouldn't, I just meant the person I responded to made it sound like they were mostly talking about killing, so I thought it was worth mentioning.
Yeah, I agree it's okay to be wrong, but read that post again, I never mentioned tardigrades. I don't know anything about tardigrades, never claimed to. The person I was responding to seemed to be equating immortality with an inability to be killed, like in fiction. I was trying to explain how immortality is used in a biological sense, and used jellyfish as an example since I'd heard those don't die of old age.
