A new skin

A new skin
The molting process allows the animal to grow.
Its carapace is not extendable and without this ingenious process he would feel too cramped.
The phenomenon, may take from 10 minutes to several hours depending on the individual.
 
Limestone Pro!
The moulting crayfish will squeeze out his whole body including claws, through an 'opening' (just for the occasion!) between the cephalothorax and abdomen.
Naked, it will remain vulnerable until a new envelope protects it, which can take between 10 to 27 days depending on the quality of the water it’s in.
It is through gastroliths (small limestone pieces), which it keeps in its stomach for that purpose only, and the limestone in water, it will manufacture its new outfit. So the more limestone in the water, the faster its rebirth will be!
In short:
The female crayfish moults 8 times in the first year, 4 the second, 2 the third and then once a year after that.
The male is the winner with 8 moults completed in the first year, 4 in the second, 2 in the third  year, up
