- Crayfish have good eyesight. Each eye comprises thousands of tiny structures, each functioning as a separate eye and give the crayfish a mosaic view of its world much like that of an insect.
- The two antenna and shorter and ten mules are used for touch and smell.
- Crayfish breathe through their gills (that are located underneath the exoskeleton) which extract oxygen from the water. They can also breathe air as long as their gills remain wet.
- Crayfish have a remarkable ability to regenerate lost limbs. Therefore, do not worry if one of your crayfish will lose a claw or a leg during the fight. They will regrow it after a molt or two.
