Ultrastructural studies of epidermal locomotory ciliary structures of Xenoturbella bocki, i.e. the basal part of the axaneme, the basal body and the ciliary rootlets, have revealed characters supporting the hypothesis of a close relationship between Xenoturbella and the Acoelomorpha. Some of the most prominent of these possibly synapomorphic characters are a cup‐shaped structure at the base of the axoneme, a proximally hollow rootlet arising on the anterior face of the basal body and bundles of… Expand
Ciliary ultrastructure of protobranchs (Mollusca, Bivalvia)
TLDR
The external epithelial cilia and other surface structures of the nuculoid protobranchs Nuculana pernula and Nucula nitidosa were studied and it was found that the basal parts of the ciliary apparatus seem to be less affected by differences in ciliary function. Expand
Ciliary ultrastructure of neomeniomorphs (Mollusca, Neomeniomorpha = Solenogastres)
TLDR
The presence of two ciliary rootlets likely represents the basal plesiomorphic state for the Bilateria and is congruent with the hypothesis of a basal position of these taxa within the Mollusca. Expand
Ultrastructure of epidermal cilia and ciliary rootlets in Scaphopoda
TLDR
The discovery of an anterior rootlet in Scaphopoda shows that the presence of paired ciliary rootlets is not a synapomorphy of a clade comprising the aplacophoran Neomeniomorpha and Chaetodermomorpha, but that it represents a plesiom orphy of the Mollusca. Expand
Ultrastructure of gill cilia and ciliary rootlets of Chaetoderma nitidulum Lovén 1844 (Mollusca, Chaetodermomorpha)
TLDR
The epithelial structures of Chaetoderma show similarities with other Mollusca, but there are no structural characters that could support the current hypothesis of a close relationship of Xenoturbella to the MLLusca. Expand
New light on the enigmatic Xenoturbella (phylum uncertain): ontogeny and phylogeny
  • O. Israelsson
  • Biology
  • Proceedings of the Royal Society of London. Series B: Biological Sciences
  • 1999
TLDR
The previously unknown embryology of Xenoturbella is reported here that unequivocally corroborates a bivalve relationship and thus once and for all dismisses the potential new phylum plesiomorphic phylum. Expand
Xenoturbella is a deuterostome that eats molluscs
TLDR
It is shown that the samples in these studies were contaminated by bivalve embryos eaten by Xenoturbella and that XenOTurbella is in fact a deuterostome related to hemichordates and echinoderms. Expand
Xenacoelomorph-Specific Hox Peptides: Insights into the Phylogeny of Acoels, Nemertodermatids, and Xenoturbellids
TLDR
Results from the decoded genome of the acoel Praesagittifera naikaiensis and reported xenacoelomorph Hox genes revealed that acoels share a peptide NLK(S/T)MSQ(V/I)D, which starts immediately after the homeodomain sequence of the central Hox4/5/6. Expand
After all: Xenoturbella is an acoelomorph!

TLDR
A study of the musculature led Ehlersand Sopott-Ehlers (1997) to place Xenoturbella as the sistertaxon of all other bilaterians, and the morphological evidence seems to be overwhelming. Expand
Epidermal ciliary ultrastructure of adult and larval sipunculids (Sipunculida)
TLDR
The ultrastructure of the ciliary apparatus of multiciliated epidermal cells in larval and adult sipunculids is described and the phylogenetic implications discussed and no possible synapomorphic character with the phylogenetically troublesome Xenoturbella was found. Expand
The Acoela: on their kind and kinships, especially with nemertodermatids and xenoturbellids (Bilateria incertae sedis)
TLDR
It becomes successively clearer that acoelomorphs are a “basal” but “divergent” branch of the Bilateria. Expand

The ciliated epidermis of Xenoturbella bocki (Platyhelminthes, Xenoturbellida) with some phylogenetic considerations
TLDR
The epidermis of Xenoturbella bocki Westblad was studied by scanning and transmission electron microscopy and showed a characteristic pattern of axonemal filament termination in the distal tips of their cilia, which may be an apomorphic feature which indicates a close relationship between xenoturbellida, Nemertoder‐matida and Acoela. Expand
Comparative ultrastructure of the epidermal ciliary rootlets and associated structures in species of the Nemertodermatida and Acoela (Plathelminthes)
TLDR
The epidermal ciliary structures in species of the Nemertodermatida and Acoela have a number of shared characters which are unique within the Plathelminthes, but almost all of these characters are found in Xenoturbella bocki (Xenoturbellida), and some even inspecies of other ”phyla” of the ”lower” Metazoa. Expand
Ultrastructure of the subepidermal musculature of Xenoturbella bocki, the adelphotaxon of the Bilateria
TLDR
Xenoturbella bocki is hypothesized to be the sister taxon of the Bilateria, the high-ranked taxon Xenoturbellida that lives on marine mud bottoms at a depth of 20–120 m and moves extremely slowly by ciliary gliding. Expand
Ultrastructural Observations on the Epidermis of Xenoturbella bocki Westblad, 1949; With a Discussion of Epidermal Cytoplasmic Filament Systems of Invertebrates
TLDR
The conclusion must be that it is still not possible to assign an appropriate place for this animal in the systematic-phylogenetic system. Expand
Comparative morphology of statocysts in the Plathelminthes and the Xenoturbellida
The general fine-structural organization of statocysts in Catenulida, Nemertodermatida, Acoela, Proseriata, Lurus (Dalyellioida), and Xenoturbella are summarized. In lithophorous (statocyst-bearing)Expand
Fine Structure and Function of Pharynx Cilia in Glossobalanus minutus Kowalewsky (Enteropneusta)
TLDR
A model for mucus and water currents through gill slits is postulated and a ciliary specialization can be found in order to move a determinate substance, i.e. mucus or water. Expand

  • 1965
TLDR
Five species of acoelous turbellarians have been studied: Convoluta roscoffensis Graff, C. convoluta, Aphanostoma diversicolor Oersted, Otocelis rubropunctata, and Avagina incola Leiper, and a method that yields adequate results with acOel material is described. Expand

TLDR
The unique structure of these cilia has systematic and phylogenetic significance for the Acoela, and it is argued that ultrastructural characters in general, including characters of organelles, can be validly applied to the phylogeny and systematics of the Metazoa. Expand
Fine‐Structure and Evolutionary Implications of the Frontal Organ in Turbellaria Acoela. 1 Diopisthoporus gymnopharyngeus sp.n.
TLDR
Similarities between the body wall glands and the frontal glands in D. gymnopharyngeus are in accord with von Graff's hypothesis that the frontal organ in acoels evolved from an anterior accumulation ofBody wall glands, and support the relatively primitive position of the Diopisthoporidae within the Acoela postulated from earlier studies of the parenchyma.

TLDR
Previous indications of distinct similarities between certain characteristics of the epidermis and the SMC present in both enteropneusts and in Xenoturbella are strengthened. Expand
