Molting occurs when and because they need to grow. Crayfish have exoskeletons which means they have a hard, protective shell on the outer layer of their body. They need to grow out of their shells to gradually get bigger.

Why do crayfish shed their skin?
Crayfish shed their shells because they are growing. they do not shed their skin, but rather the inflexible shell on top. Because it is inflexible, it cannot grow with the crayfish and they have to make new ones. Replacing a shell is called "molting". crayfish and other crustaceans molt more when they are young and are growing faster. Hope this helps!
What are some problems inherent in molting?
Growth occurs by molting, or ecdysis. In many arachnids the first molt occurs while the animal is still within the egg. ... Growth can occur only by shedding the old exoskeleton, a process termed molting or ecdysis.
Does molting occur in arthropods at immature stage?
Yes. In most arthropods, molting occurs at the end of every juvenile phase to allow the individual to accumulate more mass and bigger size while still retaining the exoskeleton. Molting usually ends once the animal achieves adult size, such as with insects and many arachnids. In other arthropods, such as with crabs, lobsters and tarantulas, molting continues even in adulthood.

How is the exoskeleton on a crayfish an adaptive advantage?
The exoskeleton on the crayfish is an adaptive advantage because it gives the crayfish support and protection. Unlike humans who have an internal skeleton, the exoskeleton protects the crayfish from its predators. In the case of support, the crayfish's ligament and muscles attach to the exoskeleton, which provides a structure for its internal organs and muscles. The internal skeleton, which provides support, does not provide the same protections as an exoskeleton; however, the exoskeleton also has its disadvantages such as molting. When the crayfish molts, it takes all the calcium out of its previous exoskeleton and holds it in two pockets in its head. The crayfish then flexes its posterior and pushes all the blood toward its anterior, cracking the shell. After climbing out, the crayfish is totally vulnerable to predators because it takes a couple days for the new exoskeleton, which has already developed but is thin and weak, to harden. The calcium stored from the old exoskeleton helps the new one harden, but it still takes a while.
