Weighing up to 44 lb, the Atlantic lobster is the heaviest crustacean in the world. The long and short antennae on its face not only grant it a superb sense of smell, but also allow it to pinpoint from which direction a scent is coming. These lobsters live along the east coast of North America and are a staple food source in the U.S. and Canada. Typically orange or red, Atlantic lobsters also come in a number of rarely seen colors like blue, albino, and yellow.
