The American lobster (Homarus americanus) is a species of marine crustacean found primarily along the northeastern coast of the United States and Canada. They are known for their large claws and hard shells, which can vary in color from greenish-brown to blue. American lobsters typically inhabit rocky or sandy ocean floors and can grow to be quite large, sometimes weighing over 40 pounds. These lobsters are an important part of the fishing industry, particularly in Maine, where they are harvested for their meat. They are often boiled or steamed and served in various dishes, making them a popular seafood choice. The life cycle of the American lobster includes several stages, starting from eggs to larvae and eventually to adult lobsters.
