it just does its nature
No you will have to get a glass eye.
The compound eye senses light.
A crayfish eye is small and typically black in color. It has a compound structure with many tiny lenses that allow the crayfish to see movement and changes in light. They are located on stalks on either side of the crayfish's head.
In the blink of an eye
They can certainly grow new limbs but the tail is a major body part. A small part may grow back if only slightly damaged but with major damage it is more likely the crayfish will perish.
Eye lashes do grow - although it seems like they don't. If an eyelash falls out, it will take about 4 weeks for it to grow back.
Yes.
of course they grow. you lose eye lashes all the time. if they didn't grow back, you wouldn't have any. try shaving your eyebrows off. they'll grow back! once they get to a certain point, they stop growing. that's just how your body works!
another crayfish so when they grow up they can..... you know.... "stuff"
After shedding its exoskeleton, a crayfish hides because it becomes vulnerable to injury and attacks from predators. The crayfish sheds its exoskeleton when it needs to grow. It can take two to three days for a crayfish to re-grow a new and larger one.
No the just grow back normal and will eventually grow back to normal and you have to pluck them about every 5 to 6 months or some peoples grow faster than others but no they dont grow back spiky.
