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.
An insect does this to grow. It expands rapidly before the next exoskeleton hardens.
an arthropod sheds it old exoskeleton when it has grown to a point where it needs a larger exoskeleton. This process is called ecdysis.
Yes, a crayfish can turn blue after molting due to the presence of a pigment called astaxanthin, which is usually masked by other pigments in their shell. During the molting process, the crayfish sheds its old exoskeleton and the new shell is initially soft and may appear blue before it hardens and the pigments stabilize. This blue coloration is often temporary, and as the shell hardens, the crayfish may return to its typical coloration.
An animal (insect) with an exoskeleton still grows under its exoskeleton like any other animal (insect). The exoskeleton is like a suit of armor, when the animal (insect) grows to big to fit inside its exoskeleton it sheds it, and a newer exoskeleton will grow to fit the animal (insect).
When an insect sheds its outer skin, it's called molting.
