they don't there not very social they usually kill each other for food and most stuff so there communication is really in fighting "i once caught a crayfish and it's claws were an inch long i can send you a picture give me your email at jjjmaui@gmail.com"
crayfish have one brain cell that makes their tails flip so they charge forward and another one makes the tail flip them into a quick retreat. After two crayfish fight, the winner's brain is rewired so he's always in "charge" mode. The loser goes into automatic reverse.
Crabs live alone, so the only time that they try to communicate to other crabs is when there are trying to mate. Each species of crab has a unique dance ritual that they perform.
Most of the time they actually use behavioral language
They make an odd sound, a cross between the squeak of a rusty hinge, and two hard objects grating together. This may not be the only means of communication though.
