American lobster (Homarus americanus) — A specimen weighing 20.14 kg (44 lbs 7 oz) was captured in Nova Scotia (Canada) in 1977. Based on observations made by fishers during the colonization of New England, lobsters of that period may have lived up to 150 years. The oldest age on record is 100 years old (20 kg / 43 lbs). A lobster weighing over 50 lbs was reportedly caught off the state of Maine in 1926 (unconfirmed).
