Earthworms in the class oligochaeta, which is in the phylum annelida. Ecdysis occurs in the phylum arthropoda. My guess is that earthworms' cuticles undergo a process closer to our skin's than ecdysis.
Molting is the process of secreting new cuticle. It ends into ecdysis i.e. separating new and old cuticle and shedding old cuticle. It has 3 phases preparatory, ecdysis and post ecdysis. This process ends by eclosion i.e. final emergence out of old cuticle.[Ref: insects]
Yes. A nematode is covered by a tough cuticle that is periodically shed through ecdysis.
cuticle
I thik it is the shedding of skin undergo by snakes and other reptiles.
Tapeworms have skin, intestines and reproductive organs. They are very simple creatures unlike the earthworm. Earthworms have a brain, Aortic arches, a clitellum, segments, intestines, reproductive organs, a crop, gizzard, Dorsal nerve cord, Cuticle (skin) satae, mouth and anus.
Ecdysis is when an arthropod molts its exoskeleton. Molting is necessary. The arthropod exoskeleton is inflexible, so, for it to grow larger, arthropods must molt.
It is called Ecdysis or Molting.
The shedding of the exoskeleton in insects is called molting or ecdysis. This process allows the insect to grow larger and is essential for development and survival. During molting, the old exoskeleton is shed and a new, larger one is formed underneath.

During ecdysis the blood circulation is effected due it there may be a blockage between the arteries and veins and it also causes the death of the patient.
Earthworms are covered by a thin skin called epidermis. The epidermis is covered with a thin, protective cuticle that must be kept moist to permit the passage of oxygen through it.
