Crayfish Lie!

Are All Male's Liars And Cheaters? Yes -- If They're Crayfish!

Crayfish wave their larger claw about to indicate their strength when faced with a challenging opponent.

Individuals signal their superior strength to competitors to obtain food, resolve territorial disputes and acquire mates. Current theory insists that signals of strength should be honest. Surprisingly researchers have found that dishonest signals are used routinely during dominance disputes by male Australian crayfish

Female crayfish do this too. When the actual strength of “the claw” was measured:

For female crayfish the size of the claw was an honest indication of how strong they were. However, claw size of males was not a good indicator of their strength. Males were routinely bluffing their opponents with weak claws to achieve dominance. They used claws more for intimidation than actual strength.

Once again, sounds like any bar on Saturday night.
