I want to know the answer to the following question:
What are parapodia?
All the background I'm provided with is that "Hence annelids' chetae are structurally different from the setae ("bristles") of arthropods, which are made of the more rigid α-chitin, have a single internal cavity, and are mounted on flexible joints in shallow pits in the cuticle.". Is that enough to answer the question?
Answer: no
