Nematodes are "roundworms". Pseudocoelomates, meaning the pseudocoemomate lies between the digestive track and the muscle layer. There is no muscle layes surrounding the digestive track, as it would be for coelomates, like annelids (earthworms) Platyhelminthes are "flatworms". They are acoelomates, meaning they lack body cavity between the digestive track and the body covering. There is only a tissue filled region, but no true coelom.

What else can I help you with?
Nematodes have a fluid-filled pseudocoel that serves as a skeleton?
No, nematodes do not have a fluid-filled pseudocoel as a skeleton. Nematodes have a hydrostatic skeleton, which is a combination of fluid pressure and muscles that provide support and movement. The pseudocoel is a body cavity that houses the internal organs in nematodes.
Are nematodes herbivores or carnivores or omnivores?
Nematodes can be classified as herbivores, carnivores, or omnivores, depending on the species. Herbivorous nematodes primarily feed on plant roots and tissues, while carnivorous species prey on other nematodes or microorganisms. Omnivorous nematodes exhibit a more varied diet, consuming both plant material and other small organisms. This diversity in feeding habits allows nematodes to thrive in various ecosystems.
What type of body cavity do mollusks have?
Annelids exhibit bilateral symmetry.
Are annelids herbivores?
They are invertebrates
What evidence suggests that Arthropoda might evolved from Annelids?
Annelids include earthworm,leeches and nereis;arthropods include mainly insects.THe relations between them is that both are triploblastic,coelomates,segmented body,bilateral symmetry and oviparous type of reproduction.
Are nematodes annelids?
Way different...Annilids are a phylum of the lophotrochozoa and nematodes are a phylum of ecdysozoa...

What are the invertebrate groups?
The eight groups are:* Mollusks * Echinoderms * Arthropods * Annelids * Nematodes * Porifera* Platyhelminthes * Coelenterates Or go to:What_are_the_8_groups_of_invertebrates
Do annelids have segments?
No, nematodes do not have segments. The lack of segmentation inspires their other name, roundworms. They look like smooth cylinders.
What is the difference between monecious and dioecious in mollusks and annelids?
monecious is when it has male and female reproductive organs in the same organism.
What are the phyla's?
In no particular order: Chordates Echinodermata Platyhelminthes (Flatworms) Nematodes (Roundworms) Annelids (Segmented Worms) Arthropods Porifera (Sponges) Molluscs (Shells)
Why are annelids more complex than nematodes and platyhelminthes?
Annelids have a more complex body plan than nematodes and platyhelminthes because they have segmented bodies with specialized structures like bristles (setae) and a closed circulatory system. This segmentation allows for more specialized functions in different body regions, giving annelids a higher level of complexity compared to the more simple, unsegmented body plans of nematodes and platyhelminthes.
What is the difference between nematodes and other worms?
Nematodes are triploblastic (they have an ectoderm, mesoderm and endoderm) but also have a pseudocoelom (a closed fluid-containing cavity that acts as a hydrostatic skeleton to maintain body shape, circulate nutrients, and hold the major organs). They have a thick cuticle covering their body to protect them from digestion. Just inside their gut are the longitudinal muscles; unlike other worms (annelids), the nematodes lack a circular muscle and so their movement is restricted to a side-to-side whip. The female reproductive system consists of two highly folded ovaries and two oviducts that store eggs Annelids (other worms) are also triploblastic. They are coelomate where the coelom is divided into segments and each segment can move independently. The most distinguishing feature of this group is segmentation, with the segments visible as rings around the body. Movement is by their circular muscles which expand and contract, moving the animal forward as well as side to side. Movement is also aided by the presence of bristles along the body. So basically the main difference in the two phylum is the presence or lack of circular muscle which is an important evolutionary step in annelids as it allows more effective movement.
