The correct option is (C) Grow in conjunction with shedding of their exoskeleton.
The number of species in the superphylum Ecdysozoa is staggering. This is due to the presence of two of the most varied animal phyla, the Phylum Nematoda (which includes roundworms) and the Phylum Arthropoda (the arthropods).
<h3>
What do nematodes and arthropods have in common?</h3>
- The tough external covering of Ecdysozoans, known as the cuticle, is their most obvious identifying characteristic. These animals are shielded from predators, water loss, and other elements of their environment by the cuticle, which also acts as a robust yet flexible exoskeleton.
- Every member of this superphylum undergoes periodic molting, or cuticle shedding, as they develop. They produce a fresh cuticle after molting that will protect them until their subsequent growth phase.
- The process of molting and cuticle replacement, known as ecdysis, is how the superphylum earned its name.
