A well known crustacean, much esteemed for food. Lobsters are found all round the coasts of Europe, and along the Atlantic coast of the United States north of New York. Immense quantities are sent from America to Europe, packed and preserved in hermetically sealed cans. Lobsters differ in size, weighing from 2 to 15 lbs. Their two large claws are fitted with tooth-like serrations - in the one they are many and sharp, in the other few and blunt-and with these they crash their food, which is chiefly clams, mussels, and other molluscs. They are caught in traps made either of basket-work or of netting, the bait used being dead fish. The shell of the lobster is dark-green when alive, but it turns to bright red when boiled.
