A Home for a Lobster

By Sherry Shantel

Did you ever look at a lobster swimming around in the little fish tank at a restaurant and wonder where he lived before he was caught? You may remember he lived in the ocean, but did you realize that most lobsters live in only the coastal regions around the world. Once considered unfit to eat, lobsters have risen in such popularity in the last few decades that fishermen can hardly capture enough of them to meet demand.

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.

After reaching stage four, the lobster has the swimming abilities to search for a permanent place to live. He prefers the rocky bottom of cobbles such as are found in the waters off the coast of Maine. If this isn't an option, he may choose a different habitat such as the salt peat marsh that surrounds the coast of Cape Cod. Lobsters are versatile and can survive in whatever their surroundings happen to be.

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.

After molting once more and moving into stage five of his life, the lobster moves into his new ocean bottom home. During his first year he spends the majority of his time hiding in his crevice or tunnel in order to keep from being eaten by his numerous predators. After this first year he spends a lot of time during the next three years hiding in the ocean bottom kelp and seaweed while 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.

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.

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! - 15359
