There's many of them, but here are some of the bigger ones;
Annelids, unlike roundworms (or flatworms for that matter) are segmented. That is after all how they get their name (annelida = little ring). Annelids also have a very complex organ system. Roundworms only possess a reproduction system as they usually live in an organism's intestines and don't need to digest food. Annelids posses both a reproduction system, and a digestive system as well as a circulatory system. As they are true coelomates their organs and organ systems are organised rather than just kinda' being tossed in there. =)

What are annelids?
Annelids are a type of segmented worms found in marine, freshwater, and terrestrial habitats. They have a cylindrical body with ring-like segments and exhibit bilateral symmetry. Examples of annelids include earthworms, leeches, and marine bristle worms.
What are some common African facial features that distinguish individuals of African descent from other ethnic groups?
Common African facial features that distinguish individuals of African descent from other ethnic groups include darker skin tones, broad noses, full lips, and tightly coiled hair textures. These features are often associated with the genetic diversity and unique physical characteristics of African populations.
What unique physical features distinguish a spider with a silver back and striped legs from other arachnids?
The unique physical features that distinguish a spider with a silver back and striped legs from other arachnids are its specific coloration pattern of a silver back and striped legs. This distinct color combination sets it apart from other spiders and arachnids.
The section of swollen segments in certain annelids that secretes the mucus that forms a cocoon is known as the?
The section of swollen segments in certain annelids that secretes the mucus that forms a cocoon is known as the clitellum. This specialized reproductive structure is involved in the formation of egg capsules for reproduction in annelids like earthworms.
Are annelids prokaryotic?
No. They are eukaryotic as are all animals cells.
How are earthworms and ascaris similar?
Annelids are segmented whereas roundworms are not. Annelids have a true coelom while roundworms have a pseudocoelom. Annelids have a more complex nervous system than roundworms. Annelids have a more complex circulatory system than roundworms.
Which groups of invertebrates are protostomes?
Flatworms, Roundworms, Annelids, Mollusks, and Arthropods
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.
What features does annelids and mollusks share?
their weirdness
What are Common names of animals that lack cephalization?
Which of the following groups of animals lacks cephalization? Question 4 options: Arthropods Cnidarians Roundworms Annelids
What are the phyla's?
In no particular order: Chordates Echinodermata Platyhelminthes (Flatworms) Nematodes (Roundworms) Annelids (Segmented Worms) Arthropods Porifera (Sponges) Molluscs (Shells)
What are three features shared between annelids and mollusks?
yes
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 structural features of annelids?
they are all earth worms and can be disected without dying.
What features found in annelids indicate the presence of a closed circulatory system?
blood vessels
What features of lumbricus indicate that it is an annelid?
This would include the ultrastructure of the cuticle. These creatures share this and many other features with the other annelids.
Do annelids have segments?
No, nematodes do not have segments. The lack of segmentation inspires their other name, roundworms. They look like smooth cylinders.
