Can crayfish reproduce on their own?
Scientists quickly realized the marbled crayfish were not just in German aquariums. The creatures are indeed clones of each other, all descended from a single crayfish that somehow gained the ability to reproduce on its own. They had remarkably little genetic diversity.
What color are crayfish eggs?
Eggs start out blue/black and lighten in color over time. The ones that turn orange are definitely not fertile and are discarded or eaten, so I believe you are right on that.
