Do nematodes have a Coelom?
Although nematodes do have a space in the body between the digestive tract and the body wall, it is not lined with tissue and is not considered to be a true coelom. Unlike other worms that have two bands of muscles, nematodes only have longitudinal muscles.Click to see full answer. In this way, do nematodes…

In this way, do nematodes have a body cavity?Nematodes, especially free living forms generally have a reasonably well developed nervous system. Nematodes are copiously reproductive and most of their body cavity, which is a pseudocoelom is filled with paired sets of reproductive organs, either ovaries or testes.One may also ask, do roundworms have a Coelom? Type of body cavity (coelom): Flatworms are acoelomate – they have three germ layers, but no coelom. Roundworms are pseudocoelomate – they have a cavity that forms between the mesoderm and the endoderm. Segmented worms are coelomate – they have a true coelom which forms within the mesoderm. Furthermore, do nematodes have a Pseudocoelom? Nematodes were once classified with a very large and heterogeneous cluster of animals grouped together on the basis of their overall worm-like appearance, simple structure of an internal body cavity called a pseudocoelom, and the lack of features such as cilia and a well-defined head that are found in most animals.Do nematodes have segmentation?Taxonomic level: phylum Nematoda; grade of construction: organs derived from three tissue layers; symmetry: bilateral; type of gut: complete; type of body cavity other than gut: pseudocoel; segmentation: absent; circulatory system: present; nervous system: small bundles of nerves (ganglia), two nerve cords; excretion:
