, ˈask-/

Definition of aschelminth in English:

noun (plural aschelminths or aschelminthes)

Zoology
An invertebrate animal belonging to a group of phyla that are distinguished by the lack of a well-developed coelom and blood vessels. Most are minute worm-like animals, including the nematodes, rotifers, and water bears.
Example sentences
  • Since aschelminths all lack substantial hard parts, their fossil record is extremely spotty.
  • Clearly, the status of several traditional ‘aschelminthes’ groups awaits further confirmation.
  • An alternative explanation is that it was a kind of aschelminth (pseudocoelomate worm), as indicated for example by its asymmetrical mouth.

Origin

from modern Latin Aschelminthes (former phylum name), from Greek askos 'sac' + helminth 'worm' (from the former belief that animals of this group had a fluid-filled internal sac).
