Nematodes.
Class Secernentea and class Adenophorea are both groups within the phylum Nematoda (roundworms), but they differ in several key features. Secernentea typically possess a more complex reproductive system, including a distinct esophageal structure with an anterior bulb, and they often have a more pronounced cuticle. In contrast, Adenophorea generally have a simpler reproductive structure and a less developed esophageal bulb. Additionally, Secernentea includes many parasitic species, while Adenophorea tends to consist of more free-living forms.
