cobalt blue crawfish vs blue knight lobster

How do you tell the difference between a cobalt blue crawfish and blue knight lobster with out waiting to see if it gets to be more than 6 inches?

Urg. It gets even more complicated, too. There are lots of blue lobster/crayfish species out there. Procambarus clarkii (from NA) is the one I'm getting this coming Monday, and that grows to 5 inches. But I don't know much more about differentiation...
