Which is it – lobster or crayfish?

Besides size, the major difference between lobsters and crayfish is that lobsters live in saltwater, such as oceans and seas, while crayfish live in freshwater, including lakes, rivers, streams and ponds.

A special visitor at the Open Lab is the freshwater crayfish or koura.  This little guy is in gradual decline and is ranked on the threatened species list.
