Question

Are aschelminthes segmented?

Answer 1

Aschelminthes:

1. The phylum Aschelminthes comprise bilaterian, triploblastic, and dioecious animals.
2. Example: Ascaris.
3. They are called ‘pseudocoelomates’ due to the presence of a body cavity that is not lined by mesodermal epithelium.
4. The body of segmented animals can be divided into repetitive body units (segments) both externally and internally.
5. Example: Pheretima.
6. Aschelminthes are not segmented. They have a long, thread-like body.
7. The cross-section of their body appears circular; hence they are also known as roundworms.
