Summary Introduction
Introduction:
Ecdysozoa is a superphylum that includes two groups: the arthropods and the nematodes. The word Ecdysozoa comes from the word ecdysis. The term ecdysis means the periodic shedding or molting of exoskeleton as the animal grows. This trait of ecdysis forms the basis of grouping nematodes and arthropods in Ecdysozoa.
