Where Does a Lobster Live?

By Sherry Shantel

Be it ever so humble, where does a lobster call home? Lobsters live in the coastal regions around the world. Once shunned and now cultivated for human consumption, lobsters have come to be one of the most sought-after delicacies in the world.

Right after he's born, a very tiny lobster looks nothing like an adult lobster and has a 1/1000 chance of surviving to adulthood. During the first 15 days of his life, he lives in the top three feet of water in the ocean and is extremely vulnerable to predators. During this period he molts three times before moving into the fourth stage as a miniature adult.

During the fourth stage the lobster swims very well and looks for a permanent place to live on the ocean floor. He may choose a home in a softer habitat, such as the salt marsh peat around Cape Cod, but most generally he'll choose a harder spot, such as an area with a cobble (small rocks) bottom.

Lobsters choose to live in cobble because it allows them to use its many tunnels and crevices to hide and wait for food to come drifting down. A lot of lobsters live on the Maine coast, because not only does it have the cobble bottom they want, it also has an abundance of clean, cold water.

Shortly after he molts for his fifth time, he moves to the new location he has found on the ocean bottom. For the first year or so in his new residence, he remains hidden in his tunnel or crevice so that his predators can't find him. As he gets a little larger, say after his first year there, he begins to hide in the kelp and search for food. He'll continue to do this for another three years.

Before reaching maturity our lobster will seldom attempt to swim out in the open ocean. His survival instincts tell him that it isn't safe there, and he's right. If he ventured out too far, he'd be eaten within minutes. Only when he reaches maturity does he make another move which will most like be to an area with larger rocks. Other choice residences can be in sandy or muddy areas reaching out to the edge of the continental shelf. He always looks for a one-lobster dig, because he prefers to be alone.

It's hard for a lobster to live to be very old. It has natural predators and fishermen after it no matter where it goes. Going back in history, back to a time when lobsters were plentiful and people didn't fish for them, we find records of lobsters reaching five or six feet in length.

During modern times, the largest lobster on record was caught off the coast of Nova Scotia in 1977. This monster lobster was between three and four feet long and weighed 44 lbs., 6 oz. He was thought to have been around 100 years old. Believe it, or not!
