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. (Sorry, I must have pushed some inappropriate keys)
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.
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.
Annelids exhibit bilateral symmetry.
They are invertebrates
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.
Way different...Annilids are a phylum of the lophotrochozoa and nematodes are a phylum of ecdysozoa...

The eight groups are:* Mollusks * Echinoderms * Arthropods * Annelids * Nematodes * Porifera* Platyhelminthes * Coelenterates Or go to:What_are_the_8_groups_of_invertebrates
No, nematodes do not have segments. The lack of segmentation inspires their other name, roundworms. They look like smooth cylinders.
monecious is when it has male and female reproductive organs in the same organism.
In no particular order: Chordates Echinodermata Platyhelminthes (Flatworms) Nematodes (Roundworms) Annelids (Segmented Worms) Arthropods Porifera (Sponges) Molluscs (Shells)
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.
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.
yes
annelids
Are annelids vertebrate
Annelids have an anus
