Lobsters are hard-shelled critters that are found in holes or under rocks on the bottoms of the Atlantic and Pacific oceans near the shore.  The stiff shell that covers its body looks like a suit of armor. Lobsters do not have backbones.  Lobsters do have five pairs of legs, four are used for walking, while the last set has claws.  The claws are different, one is heavy and has thick teeth to crush prey, while the other claw is smaller, and has sharp teeth for tearing apart the food.  A lobster always has its claws ready to pounce on any prey that comes near.  Most lobsters have dark blue or dark green shells.  Their shells turn bright red when they are cooked.  Lobsters eat crabs, snails, small fish, and other lobsters.  A lobster lays 5,000 to 100,000 eggs every two years.
