According to the St. Lawrence Global Observatory, lobsters prefer rocky ocean bottoms covered with algae. They can hide in the rocks, and the algae makes it easier for them to blend in. The algae also attracts food for the lobsters. When lobsters cannot find rocks, they will burrow into pebbles, sand, or clay. Lobsters stay at the entrance of their shelters, claws out so they can defend themselves.Continue Reading
National Geographic reports that lobsters are found in all the world's oceans, and even in some brackish environments and freshwater. There are hundreds of lobster types, but only a few are caught commercially. The lobsters most people are familiar with are the American and the European clawed lobsters. These cold water species are harvested commercially for human consumption. They are found on either side of the northern Atlantic Ocean.
Lobsters are found in the greatest concentrations closer to shore, in depths of up to 50 meters. However, they have been found in depths up to 700 meters. Young lobsters stay even closer to the coast, preferring depths of less than 10 meters. Adult lobsters also live closer to shore during the summer, as they prefer the warmer water, but they migrate to open water in winter. Young lobsters remain in their shelters for the winter.Learn more about Marine Life
