1. What is the scientific name?Nephropidae
2. What makes a lobster's shell special?A lobster’s shell is made of chitin and calcified proteins. It gives the lobster a hard armor that protects it from damage and keeps its body from swelling or shrinking too much. Because the shell is rigid, the lobster must shed it and grow a new one in a process called molting.
3. Why do lobsters have two different claws?Lobsters have one big, heavy claw that crushes hard shells and one smaller, sharper claw that cuts flesh. The big claw is often heavier and a bit uneven on each side. Having two different claws helps lobsters catch and eat many kinds of food.
