The American lobster, also known as the Atlantic lobster, is the largest species of lobster. Depending on its diet, genetics and exposure to light, its color can vary from greenish brown to bright blue. Around one in one million lobsters is blue like the one found at Adventure Aquarium. A genetic defect causes these lobsters to produce an excessive amount of protein, which combines with another molecule to give them a blue color. American lobsters typically have 10 legs, two with large claws of different sizes. The larger claw is used to crush; the smaller claw is used to rip. A lobster can easily snap a pencil or even a finger once in the grasp of the crusher claw. Lobsters can be either right or left handed, so some lobsters have the crushing claw on the right while others have it on the left. Scientists estimate that American lobsters may live as long as 100 years, but no one has yet figured out a way to accurately tell a lobster's age.
