Scientists have yet to find a reliable way to determine the age of lobsters. Nonetheless, they can make guesses based on geographical location, and the temperature of the water, among other things. It is thought that lobsters can live in the wild for 100 years or more. But, it is expected that average lobsters only live to be 30 years old in the wild. However, in a marine research laboratory aquarium, the oldest rock lobster to survive was 28 years old, had a 165mm carapace, and weighed 7 pounds.
Although, the number for the average age of lobsters is skewed - lobsters that reach that age are very lucky. Of all the eggs that the females release, only 1/10 of 1% survives for more than a few weeks. For example, if a female laid 10,000 eggs, 10 would survive.
Status: wild: 100 (high) years.
Status: captivity: 28 (high) years.
Status: wild: 30 years.
