From the Atlantic Coast to Lake Tanganyika: Gill-Infecting Flatworms of Freshwater Pellonuline Clupeid Fishes in West and Central Africa, with Description of Eleven New Species and Key to Kapentagyrus (Monogenea, Dactylogyridae)

open access: yesAnimals, 2021
Unlike their marine counterparts, tropical freshwater clupeids receive little scientific attention. However, they sustain important fisheries that may be of (inter)national commercial interest.

Structural Characterization and Spatial Mapping of Tetrodotoxins in Australian Polyclads

open access: yesMarine Drugs, 2022
Tetrodotoxin (TTX) is a potent marine neurotoxin that occurs in several Australian phyla, including pufferfish, toadfish, gobies, and the blue-ringed octopus.

Comparative toxicity assessment of glyphosate and two commercial formulations in the planarian Dugesia japonica

open access: yesFrontiers in Toxicology, 2023
Introduction: Glyphosate is a widely used, non-selective herbicide. Glyphosate and glyphosate-based herbicides (GBHs) are considered safe for non-target organisms and environmentally benign at currently allowed environmental exposure levels.

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.

Region-specific regulation of stem cell-driven regeneration in tapeworms

open access: yeseLife, 2019
Tapeworms grow at rates rivaling the fastest-growing metazoan tissues. To propagate they shed large parts of their body; to replace these lost tissues they regenerate proglottids (segments) as part of normal homeostasis.

Complete mitogenome of the invasive land flatworm Parakontikia ventrolineata, the second Geoplanidae (Platyhelminthes) to display an unusually long cox2 gene

open access: yesMitochondrial DNA. Part B. Resources, 2020
We sequenced the complete mitogenome of the invasive flatworm Parakontikia ventrolineata (Platyhelminthes, order Tricladida, family Geoplanidae). The genome is 17,210 bp long, and displays common unusual characteristics shared with Platydemus manokwari ...

Genome-wide analyses reveal a role for peptide hormones in planarian germline development. [PDF]

open access: yesPLoS Biology, 2010
Bioactive peptides (i.e., neuropeptides or peptide hormones) represent the largest class of cell-cell signaling molecules in metazoans and are potent regulators of neural and physiological function.

Including planocerid flatworms in the diet effectively toxifies the pufferfish, Takifugu niphobles

open access: yesScientific Reports, 2018
Beginning with the larval stages, marine pufferfish such as Takifugu niphobles contain tetrodotoxin (TTX), an extremely potent neurotoxin. Although highly concentrated TTX has been detected in adults and juveniles of these fish, the source of the toxin ...
