This paper presents an ultrastructural study of Cavisoma magnum (Acanthocephala, Cavisomatidae) with a Transmission Electron Microscopy tool. This parasite of the fish Siganus lineatus is here reported for the first time from off New Caledonia, South Pacific. It is the first study describing the ultrastructure, spermiogenesis and spermatozoon of a species of the family Cavisomatidae. Any nematode of the genus Habronema. , Journal of Comparative Pathology and Therapeutics: The identification of the parasites is at present impossible, but the spinous-tipped tail indicates that they correspond to certain stages of one of the spiruroidea, and so most probably of a habronema; whether Habronema muscæ, microstoma, or megastoma must be.

The third volume of "The Invertebrates" completes Miss Hyman's masterly consideration of the noncoelomate invertebrates and covers the Pseudocoelomate Bilateria which are divided into the phyla, Acanthocephala, Aschelminthes and Entoprocta.
The name Nemathelminthes has been abandoned for Aschelminthes as it has been used for so many different by: The Invertebrates: Acanthocephala, Aschelminthes, and Entoprocta - The Pseudocoelomate Bilateria (Volume III).

[Libbie Henrietta Hyman]. Acanthocephala (Greek ἄκανθος, akanthos, thorn + κεφαλή, kephale, head) is a phylum of parasitic worms known as acanthocephalans, thorny-headed worms, or spiny-headed worms, characterized by the presence of an eversible proboscis, armed aschelminthes spines, which it uses to pierce and hold the gut wall of its host.
Acanthocephalans have complex life cycles, involving at least two hosts Clade: Gnathifera. Vertebrates and Invertebrates. Acanthocephala (Book Reviews: The Life of the Spider; The Invertebrates: The Pseudocoelomate And entoprocta book Acanthocephala, Aschelminthes, and Entoprocta).
The phyla Priapulida and Entoprocta are sometimes included as well (Hyman, ; Hickman, ). All are “ pseudocoelomate,” possessing a central body cavity that contains the internal organs and gives the organism a tube-within-a-tube structure. Aschelminth, a name referring to an obsolete phylum of Acanthocephala invertebrates, mostly of microscopic size.
Previously, Acanthocephala Aschelminthes included seven diverse classes of animals: Nematoda (or Nemata), Rotifera, Acanthocephala, Gastrotricha, Kinorhyncha (or Echinodera), Nematomorpha, and.

So strong are the centrifugal and fractionating forces in modern science that one maywell wonderwhether, even by loose analogy, Newton's third law has any validity here-whether in fact there are any effective agents.
The phylum of Aschelminthes comprises five classes: Rotifera, Gastrotricha, Kinorhyncha, Nematomorpha and Nematoda, and is characterized by the presence of a pseudocoelom.
However, the taxonomic disposition of these groups has always been troublesome to zoologists 1, and some authors 2,3 proposed treatment of these groups as separate phyla. External morphology of the eggs of Asplanchnopus multiceps (Schrank, ) (Rotifera): solving the year-old case of mistaken identity.

Acanthocephala is a small group of obligate parasites that utilize arthropods and vertebrates in a conserved two-host life cycle.
The name of the phylum refers to the thorny retractable proboscis that anchors the adult worm to the intestine of the vertebrate host. The invertebrates, Vol. III, Acanthocephala, Aschelminthes, and Entoprocta.
1. The anatomy of the cephalic ganglion and associated nerves in the Acanthocephalan Macracanthorhynchus hirudinaceus has been studied preliminary to use of the organ as a model system for the study of neural pathways.
Analysis of routine serial sections of the anterior portion of the worm revealed the existence of eighty-six cells within the cephalic ganglion itself. 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.
