A new species of freshwater kamptozoan (Entoprocta) is described from the Mae Klong and Prachin Buri Rivers in central Thailand. This brings to two the number of known entoproct species occurring in fresh water. The new species, Loxosomatoides sirindhornae, grows as stolonate colonies; each diminutive zooid has a muscular, unsegmented stalk, and an obliquely oriented calyx. A well-formed hibernaculum originates from a short, lateral stolon at the base of certain zooids. The calyx bears a rigid… 
Emschermannia ramificata-a new genus and species of solitary entoproct from the Kara Sea, Russia.
The morphology of Emschermannia may be considered intermediate between that of solitary and colonial forms, with relevance to evolutionary development within Entoprocta.
Review of the Studies of Japanese Entoprocts (Entoprocta)
The study of entoprocts in Japanese waters was begun in 1890 by Asajiro Oka, who described 1 colonial species from central Japan. To date, 30 solitary and 11 colonial species have been reported from
Trapped in freshwater: the internal anatomy of the entoproct Loxosomatoides sirindhornae
The architecture of internal organ systems such as the musculature or the calyx-stalk junction hold more promising information for taxonomic and perhaps even evolutionary inferences in Entoprocta than external characters such as spination.
Checklist dos Entoprocta do Estado de São Paulo, Brasil
There are no experts on Entoprocta neither in Sao Paulo nor in Brazil, and due the low diversity of this phylum, it is only justified the capacitation of experts who also embrace other taxa, such as EctoproCTa (Bryozoa).

The neuroanatomy of Barentsia discreta (Entoprocta, Coloniales) reveals significant differences between bryozoan and entoproct nervous systems
The neuroanatomy of the colonial Barentsia discreta is generally similar to that of solitary entoprocts but differs in the anatomy and ultrastructure of the ganglion, the number of neurite bundles in the calyx, and the distribution of serotonin in the nerve elements.
Filamentous Connections between Ediacaran Fronds
Immunocytochemistry of the neuromuscular systems of Loxosomella vivipara and L. parguerensis (Entoprocta: Loxosomatidae)
Comparison of the myo‐anatomy of adults and asexually produced budding stages of the solitary entoproct species Loxosomella vivipara and L. parguerensis indicates that longitudinal and diagonal body muscles, atrial ring muscles, tentacle muscles, esophageal and rectal ring muscle, as well as intestinal and anal sphincters are probably part of the ancestral entop roct muscle bauplan.
Freshwater biodiversity in the rivers of the Mediterranean Basin
A comparison of the ecological and biological traits of endemic and non-endemic species of three riverine groups revealed that endemic species have several strategies and mechanisms to face typical mediterranean-climate conditions, such as drought, when compared to non- endemic species.


Loxokalypus socialis gen. et sp. nov. (Kamptozoa, Loxokalypodidae fam. nov.), ein neuer Kamptozoentyp aus dem nördlichen Pazifischen Ozean. Ein Vorschlag zur Neufassung der Kamptozoensystematik
It is proposed that illustrations for new descriptions of entoprocts should be standardized, and that the use of microphotos for this purpose be made obligatory, and a new approach proposed to the taxonomy of Kamptozoa consistent with phylogeny.

This is the first detailed consideration of anthropogenic influences on kamptozoan distributions, and it is emphasized that most kamPTozoan species are cryptogenic pending further investigation.

For more than a decade at Wright State University the authors have maintained continuous laboratory communities of freshwater invertebrate species, and the species shown in Figure 1 are among many currently growing in their systems.
