Interesting bit of info we noticed on the Lobster Wikipedia page:

Recent research has led scientists to believe that lobsters may be one of a small number of species which do not die of aging. Lobsters do not slow down, weaken, or lose fertility with age. In fact, older lobsters are more fertile than younger lobsters. The reason for this indefinite longevity is said to be due to telomerase, an enzyme that repairs DNA sequences. … In fact, lobsters may exhibit negligible senescence, in that they effectively live indefinitely, barring injury, disease, capture, etc.
