Diversity, 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.

Cell 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.

Journal 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]
Invertebrate 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

TTX-Bearing Planocerid Flatworm (Platyhelminthes: Acotylea) in the Ryukyu Islands, Japan
Marine Drugs, 2018 Polyclad flatworms comprise a highly diverse and cosmopolitan group of marine turbellarians. Although some species of the genera Planocera and Stylochoplana are known to be tetrodotoxin (TTX)-bearing, there are few new reports.
