Free-living clinging flatworms (Rhabditophora, Polycladida) associated with Sargassum from the Caribbean Coast of Colombia [PDF]

open access: yesBiodiversity Data Journal
Polyclads are a diverse group of marine free-living flatworms, with some species adapted to life in floating Sargassum mats. Recent studies suggest that, rather than being inherently pelagic, these flatworms should be classified as "clinging fauna ...

Sticking Together an Updated Model for Temporary Adhesion [PDF]

open access: yesMarine Drugs, 2022
Non-parasitic flatworms are known to temporarily attach to the substrate by secreting a multicomponent bioadhesive to counteract water movements. However, to date, only species of two higher-level flatworm taxa (Macrostomorpha and Proseriata) have been ...

A World of Viruses Nested within Parasites: Unraveling Viral Diversity within Parasitic Flatworms (Platyhelminthes) [PDF]

open access: yesMicrobiology Spectrum, 2022
Because parasites have an inextricable relationship with their host, they have the potential to serve as viral reservoirs or facilitate virus host shifts.

Morphology and phylogeny of two acotylean flatworms (Platyhelminthes, Polycladida) from the genera Cryptophallus and Limnoplana in the South China Sea [PDF]

open access: yesZooKeys
We describe two new species of the genera Cryptophallus Bock, 1913 and Limnoplana Faubel, 1983, which have not been reported for nearly a century. Herein, the genus Limnoplana represents a rare group of polyclads inhabiting brackish waters. Cryptophallus

Fantastic Flatworms and Where to Find Them: Insights into Intertidal Polyclad Flatworm Distribution in Southeastern Australian Boulder Beaches

open access: yesDiversity, 2023
There is a rapid and extensive decline of our marine biodiversity due to human impacts. However, our ability to understand the extent of these effects is hindered by our lack of knowledge of the occurrence and ecology of some species groups.

The ultrastructure of the apical organ of the Müller's larva of the tiger flatworm Prostheceraeus crozieri

open access: yesCell Biology International, Volume 47, Issue 8, Page 1354-1367, August 2023., 2023
Abstract The tiger flatworm Prostheceraeus crozieri (Polycladida) develops via an eight‐lobed, and three‐eyed planktonic Müller's larva. This larva has an apical organ, ultrastructural details of which remain elusive due to a scarcity of studies.
