Here’s an article entitled “Lobsters may hold the key to eternal life.”
I don’t know that “eternal” is quite the right word for it. But certainly “very long” would seem to fit.
Apparently it’s all in the telomeres:
Although they are still susceptible to death by disease or attacks, lobsters can theoretically live forever because getting older does not raise their chance of dying.
An enzyme known as telomerase prevents the DNA in lobsters’ cells from being damaged as they are replicated, scientist Simon Watt reports in The Sun.
Does that make you feel more guilty about eating lobster? Or does it make you feel better about it?
