I'm guessing they are caught in freshwater? look similar to our freshwater crays, known as "yabbies"....I spent many hours as a kid catching, cooking and shelling them...lots of work for the sweet tail.
The shells stink to high heaven after a few days in the trash bin...always dumped them in somone else's.. <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/kewl.gif" alt="" />
The simple things in life are always the best.

Excuses are for losers.
