To be or not to be a flatworm: the acoel controversy.

open access: yesPLoS ONE, 2009
Since first described, acoels were considered members of the flatworms (Platyhelminthes). However, no clear synapomorphies among the three large flatworm taxa -- the Catenulida, the Acoelomorpha and the Rhabditophora -- have been characterized to date ...

Genome-Wide Characterization of the Nuclear Receptor Gene Family in Macrostomum lignano Imply Its Evolutionary Diversification

open access: yesFrontiers in Marine Science, 2021
Nuclear receptors (NRs), a series of key transcription factors that are mostly activated by endogenous ligands or environmental xenobiotics, are reportedly good phylogenetic markers of animal genome evolution. As the early diverging class of bilaterians,

Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia

open access: yesEuropean Journal of Taxonomy, 2021
The systematics and distribution of the order Polycladida within the Macaronesian archipelagos are analysed. New species (Marcusia alba sp. nov., Prostheceraeus crisostomum sp. nov., Parviplana sodade sp. nov., Euplana claridade sp. nov., Stylochus salis

First Detection of Tetrodotoxins in the Cotylean Flatworm Prosthiostomum trilineatum

open access: yesMarine Drugs, 2021
Several polyclad flatworm species are known to contain high levels of tetrodotoxin (TTX), but currently TTX-bearing flatworms seem to be restricted to specific Planocera lineages belonging to the suborder Acotylea.

Limnoterrestrial ‘Typhloplanidae’ (Rhabdocoela, Platyhelminthes), with the description of four new species and a new genus

open access: yesEuropean Journal of Taxonomy, 2022
Four new species of limnoterrestrial rhabdocoels (‘Typhloplanidae’ Graff, 1905) are described. One of these – Faunulus nielsi Houben, Proesmans & Artois gen. et sp. nov. – could not be unambiguously placed within an existing genus.

The tapeworm interactome: inferring confidence scored protein-protein interactions from the proteome of Hymenolepis microstoma [PDF]

open access: yes, 2020
BACKGROUND: Reference genome and transcriptome assemblies of helminths have reached a level of completion whereby secondary analyses that rely on accurate gene estimation or syntenic relationships can be now conducted with a high level of confidence ...

Serotonin Signalling in Flatworms: An Immunocytochemical Localisation of 5-HT7 Type of Serotonin Receptors in Opisthorchis felineus and Hymenolepis diminuta

open access: yesBiomolecules, 2021
The study is dedicated to the investigation of serotonin (5-hydroxytryptamine, 5-HT) and 5-HT7 type serotonin receptor of localisation in larvae of two parasitic flatworms Opisthorchis felineus (Rivolta, 1884) Blanchard, 1895 and Hymenolepis diminuta ...

Epizoic acoelomorph flatworms compete with their coral host for zooplankton [PDF]

open access: yes, 2011
Satisfying nutrient requirement of corals is still a major constraint for maintaining corals in marine aquariums. Corals are polytrophic in nature. Heterotrophic feeding on zooplankton is one of the corals’ strategies to overcome nutrient deficiency ...

Epizoic acoelomorph flatworms impair zooplankton feeding by the scleractinian coral Galaxea fascicularis

open access: yesBiology Open, 2012
Summary Many scleractinian coral species host epizoic acoelomorph flatworms, both in aquaculture and in situ. These symbiotic flatworms may impair coral growth and health through light-shading, mucus removal and disruption of heterotrophic feeding.

Biological controls to manage Acropora-eating flatworms in coral aquaculture

open access: yesAquaculture Environment Interactions, 2020
Coral aquaculture is expanding to supply the marine ornamental trade and active coral reef restoration. A common pest of Acropora corals is the Acropora-eating flatworm Prosthiostomum acroporae, which can cause colonial mortality at high infestation ...
