it just does its nature
No you will have to get a glass eye.
The compound eye senses light.
A crayfish eye looks like a beanie baby animal's eye. It looks like a tiny little black pebble. The eyes stick out of the side of the crayfish's head.
In the blink of an eye
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.
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.
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"
yes, I have burned them off before. and they came back
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.
