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.
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.
Yes; although most of them are bisexual, very few of them, like Schistosoma, are dioic, having separate masculine and feminine organisms.
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.
All members of the Annelida phylum are segmented worms. These are more commonly known as earthworms.
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.
No, flatworms are from the phylum Platyhelminthes, while worms are from the phylum Annelidia. Worms are more developed and have a coelum, while flatworms have no coelum at all.
Brief answer only. Phyllum Platyhelminthes are the flatworms. These have three layers of cells. Phyllum Annelidia are the segmented worms. These have blood vessels, a developed nervous system, and a digestive system organized round a central tube.
Mosquitoes and (Crane) flies are all closely related. They are much more closely related to each other than to segmented worms.
Flatworms, belonging to the phylum Platyhelminthes, are simple, soft-bodied invertebrates with bilateral symmetry and no body cavity (acoelomates). In contrast, arthropods, which include insects, arachnids, and crustaceans, belong to the phylum Arthropoda and have a segmented body, a hard exoskeleton made of chitin, and a true coelom. Additionally, arthropods exhibit jointed appendages and complex nervous systems, whereas flatworms have a more rudimentary structure and lack specialized respiratory and circulatory systems.
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.
