Lobster Biology
But lobsters who have claws often have claws of different sizes, for example the king crab. These unequal claws are for special actions. When a fisherman catches a lobster, the lobster's claw is often full and fleshy, not small. Lobsters have a cephalothorax which is the place where their head connects to the thorax. The carapace covers the cephalothorax and the thorax. The carapace is made of chitin. A lobster's head has two pairs of antennae and three pairs of jaws. Lobsters use their antennae to feel where they are. They cannot see very well.
