Aschelminth

From Wikipedia, the free encyclopedia
(Redirected from Aschelminthes)

Template:Short description The Aschelminthes (Aeschelminthes or Nemathelminthes), 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:

Gnathifera

Nematoidea

Scalidophora

In addition, Cycliophora, Entoprocta[3] and Tardigrada are sometimes included.[4]
