Phylum—Aschelminthes or Nemathelminthes or Nematoda (Nema — thread; helminth — worms) includes roundworms. They are commonly called as nematodes. The term “Aschelminthes” was proposed by Grobben. The body of the aschelminthes is circular in cross-section, hence, the name roundworms. @ @hindiacademy2024 @nrkacademy
