A bit about lobsters

It has been estimated that lobsters live up to 70 years old, although determining age is difficult. In 2012 a report was published describing how growth bands in calcified regions of the eye stalk or gastric mill in shrimps, crabs, and lobsters could be used to measure growth and mortality in decapod crustaceans. Without such a technique, a lobster’s age is estimated by size and other variables; this new knowledge “could help scientists better understand the population and assist regulators of the lucrative industry”.
