Question

Quizplus · Accepted Answer

Nematodes are characterized by having a pseudocoelom, a complete digestive system, and bundles of longitudinal muscles extending the length of their body. However, they do not have a well-developed respiratory system. Instead, they rely on diffusion to exchange gases with their environment. They also lack a hydrostatic skeleton, which is a feature found in some other invertebrate groups such as cnidarians and annelids.
