The Aschelminthes (also known as Aeschelminthes, Nemathelminthes, Nematodes), closely associated with the Platyhelminthes, are an obsolete phylum of pseudocoelomate and other similar animals that are no longer considered closely related and have been promoted to phyla in their own right.
Why Aschelminthes are called Pseudocoelomates?
In Aschelminthes, the body cavity is not lined by mesoderm, instead, the mesoderm is present as scattered pouches in between the ectoderm and endoderm. Hence, they are called pseudocoelomates.
Which one is not Aschelminthes?
Flatworms (Platyhelminthes) are acoelomates ie they lack a coelom. Molluscs and Insects (a type of Arthropods) are coelomates having a true coelom. Roundworms (Aschelminthes) are pseudocoelomates in which the coelom is not derived from mesoderm.
Does Ascaris show Metamerism?
Ascaris belong to the phylum Nematoda of super phylum Aschelminthes. They have a cylindrical body without showing any metamerism, a pseudocoel (false coelom) and a complete digestive tract lined by endodermal epithelium.

Does Hirudinaria show Metamerism?
ADVERTISEMENTS: The body of leech is divided metamerically into segments or somite’s but metamerism is much reduced and the number of segments, unlike other annelids, is fixed in leeches, they always have 33 segments or somite’s.
What are the characteristics of Ascaris?
Ascaris lumbricoides is also known as the common roundworm. The roundworms are different from the flatworms and tapeworms as they have cylindrical body, pseudocoelom and a complete digestive tract lined by endodermal epithelium. Most of these round worms are free living but some parasitic worms also exist.
What are the two types of Ascaris egg?
Since 2 morphological forms (fertilized and unfertilized) of egg can be produced by Ascaris, infected humans can release in their faeces fertilized eggs only (FEO), unfertilized eggs only (UEO) or both fertilized and unfertilized eggs (FUE) (designated herein as the 3 different egg profiles).
Where are Ascaris found?
Ascaris lives in the intestine and Ascaris eggs are passed in the feces of infected persons. If the infected person defecates outside (near bushes, in a garden, or field), or if the feces of an infected person are used as fertilizer, then eggs are deposited on the soil.
Which of the following is correct for Ascaris?
Ascaris requires a single host, i.e., man to complete its life cycle. The most important locations in body of man where Ascaris visits are small intestine and from there it migrates to the lungs through pulmonary circulation where they almost ten times bigger and moult twice. Thus, the correct answer is option C.
