Lobster Fact:
A lobster molts about seven times the first year, then at a slower rate from that point on. From first stage larva to adult legal size, the lobster has molted between 25 to 27 times. It is estimated that a one-pound lobster may be five to seven years of age. With each molt, a legal-sized lobster may increase in carapace length by 14% and gain 40-50% in weight. The record for the largest documented lobster goes to one taken off Nova Scotia in 1977. It weighed 44 pounds, six ounces and may have been 100 years old.
