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.

To see a newborn lobster, you could never imagine it growing up to look like an adult lobster. It is incredibly tiny and misshapen, and its chances of living to reach the adult stage is only 1 in a thousand. While he spends his first two weeks of life floating near the surface of the ocean, he is easy prey for any fish that comes swimming by him. If he lives as long as the fourth stage of life, he will have molted 3 times.

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.

Cobble is an exceptionally suitable habitat for lobsters. There are many crevices and cracks around and under the small rocks that make up the cobble which offers him places to hide and wait for his food to come to him. While many coastal regions offer rocky bottoms, Maine is ideal in that it also has just what lobsters like, clean, cold water.

The lobster moves into his new, ocean bottom home when he molts into stage five. During his first year or so he lives in a tunnel or crevice underneath the cobble where his many predators won't be able to find him. From his first year until about his fourth year, he hides in the seaweed and the kelp as he cruises around looking for food.

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.

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.

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! - 29974
