Lobsters are usually the same on the left and right sides. Lobsters have claws on their front legs, and one claw can be bigger than the other. One reason they are different sizes is because they do different jobs. Big strong claws can grab food, and little sharp claws can cut the food up so they can eat it. When a fisherman catches a lobster, they like to keep them if the claws are big. People like to eat lobsters with big claws because there is more good tasting meat in them. The head end of the lobster is called the cephalon. The middle part of the lobster is called the thorax. These parts of a lobster are stuck together and can not move, so we put the words together and call them both the cephalothorax. The bottom end of the lobster is called the abdomen, where the tail is. At the end of the tail is a fan. Lobsters have long thin body parts called antennae under their eyes which they can move around. Lobsters use these to feel what is near them, and they also help them find food. Lobsters have eyes but they cannot see very well. Lobsters have three pairs of jaws. All legs of a lobster have claws apart from the ones at the back. Only the front two legs have big claws. The little claws on the other legs help pick up food they find and put them in the jaws so the lobster can eat.
