4. Lobsters

Lobsters have long intrigued scientists because they keep growing and molting throughout their lives, showing few signs of typical aging. This impressive longevity may be linked to their continuous production of telomerase—an enzyme that repairs DNA and protects cells from aging.
Unlike many other crustaceans, lobsters don’t seem to slow down or weaken with age. According to Smithsonian Magazine, this unique biology sets them apart, although they are still vulnerable to disease and injury in the wild.
