What is the difference between nematodes and annelids?
Nematodes are roundworms with smooth bodies and a lack of segmentation, while annelids are segmented worms with ring-like divisions along their bodies. Annelids also have bristles called setae on their bodies, which nematodes lack. Additionally, nematodes have a protective cuticle covering their bodies, while annelids do not.
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 are the phyla's?
In no particular order: Chordates Echinodermata Platyhelminthes (Flatworms) Nematodes (Roundworms) Annelids (Segmented Worms) Arthropods Porifera (Sponges) Molluscs (Shells)
How many types of worm are there and what specif tpes are there?
There are three main types of worms: annelids (segmented worms), nematodes (roundworms), and platyhelminthes (flatworms). Annelids include earthworms and leeches, while nematodes encompass many species like Ascaris and Caenorhabditis elegans. Platyhelminthes feature species such as planarians and tapeworms. Each type plays a unique role in ecosystems and has distinct biological characteristics.
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.

HOW ROUNDWORMS AND ANNELIDS DIFFERENT?
Roundworms, or nematodes, are unsegmented, cylindrical worms with a tough outer cuticle and a simple body structure, lacking specialized respiratory and circulatory systems. In contrast, annelids, such as earthworms, are segmented and have a more complex body structure with a true coelom, allowing for a more advanced circulatory system and segmentation that facilitates movement. Additionally, annelids possess setae (bristle-like structures) for locomotion, while roundworms do not. These differences highlight the distinct evolutionary adaptations of each group within the animal kingdom.
Are Nematodes multi celled?
Yes. Nematodes a multicellular.
What worms are nematodes?
Nematodes belong to the roundworms or phylum Nematoda.
