Ecdysis is the moulting of the cuticle in many invertebrates. This process of moulting is the defining feature of the clade Ecdysozoa, comprising the arthropods, nematodes, velvet worms, horsehair worms, tardigrades, and Cephalorhyncha. Since the cuticle of these animals typically forms a largely inelastic exoskeleton, it is shed during growth and a new, larger covering is formed. The remnants of the old, empty exoskeleton are called exuviae.
After moulting, an arthropod is described as teneral, a callow; it is "fresh", pale and soft-bodied. Within one or two hours, the cuticle hardens and darkens following a tanning process analogous to the production of leather. During this short phase the animal expands, since growth is otherwise constrained by the rigidity of the exoskeleton. Growth of the limbs and other parts normally covered by hard exoskeleton is achieved by transfer of body fluids from soft parts before the new skin hardens. A spider with a small abdomen may be undernourished but more probably has recently undergone ecdysis. Some arthropods, especially large insects with tracheal respiration, expand their new exoskeleton by swallowing or otherwise taking in air. The maturation of the structure and colouration of the new exoskeleton might take days or weeks in a long-lived insect; this can make it difficult to identify an individual if it has recently undergone ecdysis.

A Closer Look at Molting- Ecdysis & Apolysis
Fox snake shedding
Ecdysis Official Trailer directed by Lior Khananaev Director: Lior Khananaev An obsessive scientist experiments his banned drug on a child to realize its defectiveness, as a result, the two grow older to share an intolerable hate for one another. Using DNA from a snake, Dr. Luth Femming designs a drug in hopes of changing the world. When the government prohibits the experimentation on humans, Dr. Femming confident of his work, proceeds with doing it anyway. Except his test subject is an innocent child at a park, Jace Stone. After the injection, the obsessive scientist witnesses the drug's defectiveness as snake skin overtakes the child's face. The doctor shows no pity for the child, only for himself and his failure. Years later, Jace confronts his condition and rips off the excessive sk...
