The largest lobster species in the world is American lobster, also known as North Atlantic lobster or American lobster, commonly known as Boston lobster, which is both the largest lobster and the heaviest crustacean. 1February, 977 1 1 day, someone caught a Boston lobster in Novaya Bay, Canada, weighing 20 kilograms, and it was 106 cm long from the top of the fan-shaped shrimp tail to the largest scale, which is the largest lobster caught in the world so far and the largest in the world. Boston lobster is actually called Maine lobster, and it is not produced in Boston. Originally known as North American lobster, this kind of lobster with pincers is found in the northeast of North America and even along the east coast of Canada. Because of Maine's abundant production and the first commercial fishing operation, it was named Maine lobster in the19th century. Boston lobsters can only mate for a short time after shelling. Shelling occurs about 2-3 times a year in childhood and once a year in adulthood (4-7 years old). Living in the cold sea below 600~700 meters, Boston lobster has a short life span after leaving the water and grows very slowly. Most of the Boston lobsters caught are in the range of ~ 1 kg, a Boston lobster is about 7- 10 and one pound (about 453g) longer, while a Boston lobster of 6-7kg is equivalent to growing for nearly a hundred years, so it is called "centennial lobster", and its life span is quite long, which is not clear.
