Where Does a Lobster Call Home? |
|
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. 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. 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. 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. 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. 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. The largest lobster ever captured in modern times happened off the coast of Nova Scotia in 1977. This lobster weighed 44 pounds, 6 ounces and was somewhere between three and four feet long. Experts feel it could have been as much as 100 years old. Can you believe it?
