Round worms belong to phylum Ascelminthes (nemathelminthes) ,a higher phylum than sponges (poriferans) and coelenterones.Round worms are bilaterally symmetric.which is considered as a superior quality.Also they are triploblastic and has a well developed muscular pharyx.Sexual dimorphism is also seen in round worms.
Segmented worms are more complex that coelenterates because their bodies are made up of three layers of cells, rather than two layers like for coelenterates. Each layer of cells is filled with specialized tissues and organs.
Unsegameted worms offen are larger and their shape makes them more popular since flat worms aren't noticed so the more popular the more advance.
All members of the Annelida phylum are segmented worms. These are more commonly known as earthworms.
The Segmented worms are forefathers of the most modern complex organisms. The segmentation seen in the earliest worms lead to the ability to join complex systems. So from the lowly fly to the largest whale can trace its development back to the segmented worms of the past.
longer worms have more, less, or the same segmented
the phylum is annelida, class is oligochaeta Earth worms are segmented worms so if you have any questions just google segmented worms and you will get more good sites than if you google earthworms.
Mosquitoes and (Crane) flies are all closely related. They are much more closely related to each other than to segmented worms.
Annelids (Round, Segmented worms) ; Are animals, to be more precise, invertebrates (no backbone) They are round and segmented, have no legs, and may be parasitic, aquatic or beneficial. Examples are: Earthworm and Leech
The segmented structure of segmented worms allows for greater flexibility and movement due to the ability of each segment to move independently. This allows segmented worms to navigate through their environment more efficiently. Additionally, the segmentation provides redundancy in case of damage to one segment, as the worm can still function with the other segments.
A food storage sac in segmented worms, such as earthworms, is called a crop. The crop temporarily stores ingested food before it moves on to the gizzard for grinding. This helps regulate the release of food into the digestive system for more efficient processing.
No, in fact leeches are annelida or segmented worms, like the earthworm. Sponges are something completely different, really just colonies of single cells that can also live apart. Leeches are full animals with organs and stuff.
Segmented worms, also called annelids have body parts that are duplicated in each segment. If one segment is damaged, some annelids can survive. They also have setae, or two pairs of hairs found on each segment. These hairs grip the soil and get around more efficiently.
