Can green crabs be WHITE?

Despite its name, the European green crab occasionally is not green. Juvenile green crabs especially have a high variation in their color morphology that allows them to blend into their environment. This chameleon-like ability makes them hard for us humans to see and results in their enhanced survival.

Here are some pictures taken by green crab researcher Colin O’ Neil on Isle au Haut which show green crabs of a different color.
