What are the examples of Aschelminthes?

Aschelminth/Representative species

What is the importance of Aschelminthes?

Aschelminths can be free-living or parasitic. The free-living organisms are extremely abundant in soils and sediments and they feed on bacteria. While some others are plant parasites and can cause disease in crops that are economically important.

Why Aschelminthes are called round worm?

The Aschelminthes are commonly called roundworms, because the body appears circular in the transverse cross-section. They are called pseudocoelomates because they possess pseudocoelom.

What is the other name of Aschelminthes?

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.

Do Aschelminthes have brain?

Nervous system and sensory organs- The nervous system of gastrotrichs consist of a brain and lateral nerve cords. The brain (a pair of ganglia) is located near the pharynx in the anterior portion of the body.

Do Aschelminthes have blood?

Their body walls are thin so that they can obtain oxygen from their host through their body walls in which they live as a parasite. Instead of using blood vessels for the transport of oxygen to the cells, nematodes exchange material through their skin using diffusion.

Who discovered Aschelminthes?

(ii) Grobben introduced the term Aschelminthes in 1910 instead of Nemathelminthes. Aschelminthes included the different groups of pseudocoelomate animals at the time of introduction of the term Aschelminthes. (iii) Hyman (1951) supported Aschelminthes as phylum and several classes placed under it.

Which cells are present in Aschelminthes?

Final answer: The excretory organs in Aschelminthes and Platyhelminthes, respectively, are Renette cells and Flame cells.

What is a worm called?

Worms may also be called helminths—particularly in medical terminology—when referring to parasitic worms, especially the Nematoda (roundworms) and Cestoda (tapeworms) which reside in the intestines of their host.

Do annelids have eyes?

Pigmented ocelli and eyes in Annelida. Most polychaete species have an eye of one type or another, whereas these organs are a rare exception in the large taxon Clitellata. In this group, only leeches and certain species of Naidinae possess pigmented eyes (Purschke, 2002, Purschke, 2003a).

Do Aschelminthes have blood?

Their body walls are thin so that they can obtain oxygen from their host through their body walls in which they live as a parasite. Instead of using blood vessels for the transport of oxygen to the cells, nematodes exchange material through their skin using diffusion.

Are Aschelminthes dioecious?
