Where Does a Lobster Live?

by Sherry Shantel

Most of us have eaten a lobster at least once in our life. We know they're weird-looking critters, but have you ever thought about where they come from or what type of habitat they live in? There were so many of them around during colonial times that our ancestors could pick them up by hand in ocean tide pools, even though they weren't considered proper food for anyone but the poor. Now they're an expensive delicacy which are actively farmed in order to provide for the huge demand.

A lobster newborn doesn't look much like his parents. Mother lobsters lay as many as 10,000 eggs, and if this lobster baby is real lucky, he'll be one of the 10 out of that number that lives to maturity. The mortality rate is exceptionally high amongst lobster babies. Many of them get eaten during their first two weeks of life while living in the upper three feet of the ocean. During this stage of his life, he will molt three times.

Once the baby lobster has reached stage four, he has learned to swim well. He will spend this stage looking for a permanent place to live on the ocean floor. In the coastal regions around Cape Cod, he will pick out a home in the salt marsh peat. In coastal waters around Maine, his preference will be an area with cobble (small rocks) on the bottom.

The cobble provides many hiding spots where he can just lay around and let food come drifting down to him. The coast of Maine is particularly ideal for this purpose, because the water is clean and cold with a rocky bottom.

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.

Adolescent lobsters have great survival instincts that keep them hidden for the first few years of their lives. If he were to swim out in the open ocean when he was still this young, he would be eaten within a matter of a few minutes. When he gets larger he will make another move to an area where there are larger rocks for him to hide in. He might also choose to live in a muddy or sandy area anywhere between the edge of the continental shelf and the shore. Wherever he lives, he will live alone, because he's not a social creature.

Wherever there are lobsters, there will be fishermen. Between the fishermen and natural predators, most lobsters don't live very long lives. However, historically some lobsters have been noted to have achieved larger sizes and longer life spans. Colonials, for example, recorded that some of the lobsters they found were five or six feet in length.

Lobsters don't get the chance to grow as large in this era of modern fishing techniques. The biggest one on record was caught in 1977 just off the coast of Nova Scotia. It measured in at somewhere between three and four feet, and it weighed a mighty 44 pounds, 6 ounces. It was estimated that he was around 100 years old. How about that!
