Lobsters never die of old age

Forget wrinkles and grey hairs, these crustaceans just keep on thriving!

Take a position: what's actually doing the work here?

One of these is closer than the rest. Commit before you find out.

The short version
  • Forget wrinkles and grey hairs, these crustaceans just keep on thriving!
  • Eventually, the lobster becomes so massive that the energy required to lift off its old shell is more than the lobster can produce.
  • One lobster caught off the coast of Maine was estimated to be 140 years old.

Lobsters possess an enzyme called telomerase that constantly repairs their DNA, effectively preventing 'biological aging.' Most animals' cells have a limit on how many times they can divide, but lobster cells just keep going.

An older lobster isn't a frail lobster. A 100-year-old specimen is often more muscular and more fertile than a teenager. They don't lose their appetite or their metabolism as they get older.

They only die because they literally grow too big for their own skin. Molting—the process of shedding an old shell and growing a new one—requires immense amounts of energy.
