For the first time, scientists can determine the age of a lobster, by counting its rings like a tree.  Nobody knows how old lobsters can live to be; some people estimate they live to more than 100 years old.  But knowing, rather than simply guessing, their age and that of other shellfish could help scientists better understand the poplulation and assist regulators of the lucrative industry.  Before now, scientists deudced a lobster’s age by judging their size and other variables.  But it’s now known that lobsters and other crustaceans, such as crabs and shrimp, grow one ring per year in hidden-away internal spots.
