Aschelminth

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. The term Aschelminth is now generally only used as an informal name for any member of the approximately ten different invertebrate phyla formerly included within Aschelminthes.

It is a polyphyletic group.[1]

Subdivisions

Although invertebrate experts[2] do not necessarily agree on these categorizations, groups that are generally incorporated into Aschelminthes include:

In addition, Entoprocta and Tardigrada are sometimes included.
