Molting, or in Latin, ecdysis (meaning 'to strip'!).
Through shedding their exoskeleton.
when they are shedding which is called molting it makes their new skin very soft and they could get hurt easily
an arthropod sheds it old exoskeleton when it has grown to a point where it needs a larger exoskeleton. This process is called ecdysis.
having an exoskeleton affect how an animal grows because the exoskeleton does not grow as the animal grows so the animal must shed or molt its exoskeleton.

The shedding of the outgrown exoskeleton is known as molting. Several animals do this, such as the tarantula and other arthropods.
When the organism grows, its exoskeleton cannot expand. They solve this problem by occasionally shedding their exoskeletons and grow a new and larger one. This process is called molting.
Arthropods molt (moult) in a process called ecdysis. It is necessary for growth because of the inflexibility of the exoskeleton. The old shell remnants are called exuviae. Note that the term 'anthropod' should not be confused with 'arthropod'; anthropods are humans or humanoids and do not moult in the canonic sense.
Arthropods grow by shedding their exoskeleton. Only when they shed can their bodies grow. Arthropods are very vulnerable to predators while molting so they have to have a predetermined place to hide before shedding begins.
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.
The exoskeleton of a lobser is more commonly called the shell. It is made of a protein called chitin.
