Full title: This jellyfish is the only known animal on Earth that cannot die of old age. When it gets sick or injured, it reverts back to a baby — and starts its entire life over again. Scientists call it biologically immortal.

I was reasonably sure lobsters were similar and a quick check confirms that there are a few similar animals.

tbf lobsters do die of old age, they have to molt and at some point that ends up going wrong and they die.
It's not the old age that kills them though. They molt, that goes badly and they die whilst they're vulnerable.
They don't die through the aging process.
