Crayfish, or kōura in Māori, are also called Spiny Rock Lobster. They are a creature with long antennae, no claws, and a hard 'exoskeleton' or shell which they need to cast off in order to grow bigger. In some areas it is customary for Māori to make sure that the kōura has all of it's limbs when taken. Why? If a kōura loses a leg or antenna when it is taken, other kōura might see that as a reason to leave the area!
