In biological terms, the lobster is considered an invertebrate, members of the Class Crustacea of the Phylum Anthropoda. All animals are classed according to common anatomical features. Crabs, shrimp, crayfish, water fleas, copepods, barnacles and wood lice are other crustaceans. The American lobster is found on the east coast of North America, from Newfoundland to North Carolina. In 1992, over 57 million pounds of lobsters were landed in the US, while Canadian provinces landed 94 millions pounds.
Lobsters usually move around and hunt for food at night.
It was once thought that lobsters were scavengers and ate primarily dead things. There are, however, many fish that eat baby lobsters. They generally exhibit minimal migratory behavior. Larger, more adult lobsters may inhabit deeper waters, but return seasonally to shallow warmer waters. A 1-pound female lobster usually carries approximately 8000 eggs.
