Besides the normal colored lobsters, there are also rare, yellow, red, and white ones. Except for the white ones, they all turn red when cooked.
Lobsters grow by molting.
They molt, or shed their shells, about 25 times in the first 5 years of life. No one has yet found a way to determine the exact age of a lobster because it sheds its shell so often. The teeth of a lobster are in its stomach. Lobster blood is usually a gray or slightly blue color, but it sometimes can be orange, green, or light pink. A lobster egg is the size of the head of a pin.
