The Class Bdelloidea of the Phylum Rotifera is the largest metazoan taxon in which males,
hermaphrodites, and meiosis are unknown. We conducted a molecular genetic test of this …

The Palaeacanthocephala is traditionally represented by 2 orders, Echinorhynchida and
Polymorphida, with 10 and 3 families, respectively. To test the monophyly of the class, these …

Rotifera comprise about 2,000 species (Segers 2007) of microscopic animals, usually much
less than 1 mm in length, characterized by the presence of a ciliated corona and a muscular …

Phylogenetic relationships among Syndermata have been extensively debated, mainly
because the sister-group of the Acanthocephala has not yet been clearly identified from …

The phylogeny of selected members of the phylum Rotifera is examined based on analyses
under parsimony direct optimization and Bayesian inference of phylogeny. Species of the …

Acanthocephala (thorny-headed worms) is a phylum of endoparasites of vertebrates and
arthropods, included among the most phylogenetically basal tripoblastic pseudocoelomates …

The clade Syndermata includes the endoparasitic Acanthocephala, the epibiotic
Seisonidea, and the free-living Bdelloidea and Monogononta. The phylogeny of Syndermata …

We provide molecular data (cox 1, 18S rDNA and 28S rDNA) for 17 acanthocephalan
species and 20 host-parasite combinations from Australian marine teleosts collected from off …

Phylogenetic analysis of the metazoan evolutionary tree as a whole, and of trees of
component major clades, indicates that marine herbivores, defined here as macrophagous …

Advances in morphological and molecular studies of metazoan evolution have led to a
better understanding of the relationships among Rotifera (Monogononta, Bdelloidea …
