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.

The serotonergic nervous system of prolecithophorans shows a closer similarity to fecampiids than to triclads (Platyhelminthes)

open access: yesJournal of Morphology, Volume 282, Issue 4, Page 574-587, April 2021., 2021
The nervous system in Prolecithophora has been studied for the first time using fluorescent immunocytochemistry. It consists of a brain and three longitudinal nerve cords, which are connected on either side of the body by the main lateral commissure. The ventral cords are considered as main cords and show two pairs of brain roots.

Cotylea (Polycladida): a cladistic analysis of morphology [PDF]

open access: yesInvertebrate Biology, 2008
Abstract. Polyclad flatworms are acoelomate bilaterians found in benthic communities worldwide, predominantly in marine environments. Current polyclad systematics is unstable, with two non‐concordant classification schemes resulting in a poor understanding of within‐group relationships. Here we present the first phylogenetic framework for the suborder

Larval Development in Echinoplana celerrima (Turbellaria: Polycladida)

open access: yesTransactions of the American Microscopical Society, 1984
Abstract Here, the ultrastructure of the female gonad of the marine polyclad Echinoplana celerrima was investigated using both light and electron microscopy. The female gonads are dispersed in the dorsal parenchyma between the digestive ramifications.

Characterization and phylogenetic position of two sympatric sister species of toxic flatworms Planocera multitentaculata and Planocera reticulata (Platyhelminthes: Acotylea)

open access: yesMitochondrial DNA. Part B. Resources, 2020
The complete mitochondrial genomes of two toxic flatworm species of the genus Planocera were determined. The total length of mitochondrial DNA (mtDNA) was 15,657 bp in Planocera multitentaculata and 15,486 bp in Planocera reticulata and included 12 ...

Put a tiger in your tank: the polyclad flatworm Maritigrella crozieri as a proposed model for evo-devo [PDF]

open access: yes, 2013
Polyclad flatworms are an early branching clade within the rhabditophoran Platyhelminthes. They provide an interesting system with which to explore the evolution of development within Platyhelminthes and amongst Spiralia (Lophotrochozoa).

Systematic revision of the family Pleioplanidae Faubel, 1983 (Polycladida, Acotylea): new genus and combinations

open access: yesEuropean Journal of Taxonomy, 2017
New morphological information, reconsiderations and the first combination of a generic name based on a previously established species are presented in the current revision of the family Pleioplanidae (Polycladida, Acotylea).
