My guess would have to be that since freshwater crayfish live in a hypoosmotic environment, they would produce a more dilute urine than a marine lobster because they would live in a hyperosmotic environment .

In Biology the term 'analogy' is used to describe a similar feature in a different organism, which of course is possible for most of a lobster's features. In the loose sense, one might say the freshwater crayfish is analogous to the salt-water lobster.

A crab has a round body where a lobsters body looks alot more like a giant shrimp with big pincher's crabs also have pincher's too! When you boil a crab it becomes distressed and poises its meat. Also when you boil a lobster it is blue when you put it into the pot/saucepan and pink when it comes out.
The crayfish isn't a fish at all - it is related to the lobster.
