Phylogenomics and the first higher taxonomy of Placozoa, an ancient and enigmatic animal phylum

Frontiers in Ecology and Evolution, 2022
Placozoa is an ancient phylum of extraordinarily unusual animals: miniscule, ameboid creatures that lack most fundamental animal features. Despite high genetic diversity, only recently have the second and third species been named.

An extinct clade of the basal Epitheliozoa: phylogenetic position and implication of the enigmatic Cambrian chancelloriids [PDF]

Communications Biology
The notable disparity of animal body plans can be traced back to the morphological innovations during the Cambrian explosion and represented by a number of soft-bodied and skeletal fossils that provide a compelling narrative for animal evolution ...

Placozoa and Cnidaria are sister taxa [PDF]

eLife, 2017
Abstract The phylogenetic placement of the morphologically simple placozoans is crucial to understanding the evolution of complex animal traits. Here, we examine the influence of adding new genomes from placozoans to a large dataset designed to study the deepest splits in the animal phylogeny.

Long-term dynamics of placozoan culture: emerging models for population and space biology [PDF]

Frontiers in Cell and Developmental Biology
As the simplest free-living animal, Trichoplax adhaerens (Placozoa) is emerging as a powerful paradigm to decipher molecular and cellular bases of behavior, enabling integrative studies at all levels of biological organization in the context of metazoan ...

Comparative Multi-Marker Environmental DNA Metabarcoding of Marine Metazoan Communities: Water vs. Sediment. [PDF]

Mol Ecol Resour
ABSTRACT This study investigates the metazoan biodiversity in the Southern Adriatic Sea using environmental DNA (eDNA) metabarcoding. Sediment and adjacent water samples were collected from three sites (one pristine, two impacted by human activities) at three distances from the coast across two seasons.

Parallel evolution of gravity sensing [PDF]

Frontiers in Cell and Developmental Biology
Omnipresent gravity affects all living organisms; it was a vital factor in the past and the current bottleneck for future space exploration. However, little is known about the evolution of gravity sensing and the comparative biology of gravity reception.

Studying Placozoa WBR in the Simplest Metazoan Animal, Trichoplax adhaerens

Methods in Molecular Biology, 2022
AbstractPlacozoans are a promising model system to study fundamental regeneration processes in a morphologically and genetically very simple animal. We here provide a brief introduction to the enigmatic Placozoa and summarize the state of the art of animal handling and experimental manipulation possibilities.

Bioeffects of Prunus spinosa L. fruit ethanol extract on reproduction and phenotypic plasticity of Trichoplax adhaerens Schulze, 1883 (Placozoa) [PDF]

PeerJ, 2019
The aim of this work was to test and analyse the bioeffects of Prunus spinosa L. (Rosacaee) fruit ethanol extract on Trichoplax adhaerens Schulze, 1883 (Placozoa) laboratory cultures which—for the first time—were employed as in vivo biological model to ...

Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux. [PDF]

J Exp Zool B Mol Dev Evol
Epithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.
