A phylogenomic approach to resolving interrelationships of polyclad flatworms, with implications for life-history evolution [PDF]
Royal Society Open Science, 2023 Platyhelminthes (flatworms) are a diverse invertebrate phylum useful for exploring life-history evolution. Within Platyhelminthes, only two clades develop through a larval stage: free-living polyclads and parasitic neodermatans.

The Ultrastructure of the Apical Organ of the Goette's Larvae of the Polyclad Flatworm Stylochus pilidium Indicates Homology Between Polyclad Larvae. [PDF]
Cell Biol IntABSTRACT Polyclad flatworms exhibit both direct and indirect development, with various larval types observed, including Müller's larva, Kato's larva, Goette's larva and Curini‐Galletti's larva. The different larval types are distinguished by shape, number of eyes and number of lobes.

A comprehensive comparison of sex-inducing activity in asexual worms of the planarian Dugesia ryukyuensis: the crucial sex-inducing substance appears to be present in yolk glands in Tricladida [PDF]
Zoological Letters, 2018 Background Turbellarian species can post-embryonically produce germ line cells from pluripotent stem cells called neoblasts, which enables some of them to switch between an asexual and a sexual state in response to environmental changes.

Polyclads (Platyhelminthes) in the southern Gulf of Mexico: unveiling biodiversity and descriptions of two new species [PDF]
ZooKeysThe order Polycladida (Platyhelminthes) in Mexico has historically received limited attention from researchers, primarily due to challenges associated with its low detectability and the scarcity of specialists.

Reversible shifts between interstitial and epibenthic habitats in evolutionary history: Molecular phylogeny of the marine flatworm family Boniniidae (Platyhelminthes: Polycladida: Cotylea) with descriptions of two new species. [PDF]
PLoS ONE, 2022 Tiny animals in various metazoan phyla inhabit the interstices between sand and/or gravel grains, and adaptive traits in their body plan, such as simplification and size reduction, have attracted research attention.

First Detection of Tetrodotoxins in the Cotylean Flatworm Prosthiostomum trilineatum [PDF]
Marine 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.
