The American lobster (Homarus americanus) is a species of marine crustacean found primarily along the northeastern coast of North America. It is characterized by its large claws, long antennae, and a hard shell that can vary in color from greenish-brown to blue. American lobsters inhabit rocky or sandy ocean floors and are typically found at depths of up to 500 feet. 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 as a delicacy in various dishes. The American lobster plays a significant role in marine ecosystems, serving as both predator and prey.
