The defect causes the lobsters to produce excessive levels of a protein that combines with a red carotenoid molecule known as astaxanthin. This then forms a blue complex known as crustacyanin and it is this that gives the lobsters their unusual colour.
Why does lobster turn red?
Lobsters and crabs have a pigment called astaxanthin in their shells, which has the ability to absorb blue light, making the shell appear red under certain conditions. Same goes for usually boring grey shrimp, which also have a pink pigment in their meat and shells that is released by heat.
