Shell colour variation in mollusks is a multifaceted trait governed by complex genetic mechanisms that orchestrate pigment biosynthesis, tissue differentiation and biomineralisation. Studies indicate ...

If you eat chicken eggs, you probably have a shell color preference for reasons you can’t explain. Some people only buy brown eggs because they believe they’re “healthier” or more “natural” than white ...

The blush of a lobster¿s shell during cooking is extraordinary by any measure. Exactly why the shift from purplish-blue to fiery crimson occurs has long eluded explanation. But new research is at last ...
