Global Diversity of the Placozoa

PLoS ONE, 2013
The enigmatic animal phylum Placozoa holds a key position in the metazoan Tree of Life. A simple bauplan makes it appear to be the most basal metazoan known and genetic evidence also points to a position close to the last common metazoan ancestor ...

Coordinated cellular behavior regulated by epinephrine neurotransmitters in the nerveless placozoa [PDF]

Nature Communications
Understanding how cells communicated before the evolution of nervous systems in early metazoans is key to unraveling the origins of multicellular life.

Apicortin, a Putative Apicomplexan-Specific Protein, Is Present in Deep-Branching Opisthokonts [PDF]

Biology
Apicortin, a tubulin/microtubule-binding protein, was first described in 2009 as a protein characteristic of apicomplexans; it was found to be present in all Apicomplexa genomes already sequenced.

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 ...

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 ...

Expansion microscopy in Placozoa: improving resolution and preservation of fragile samples during marine expedition

Frontiers in Marine Science
Placozoa are small disc-shaped animals representing one of the early branching metazoan lineages with only a dozen cell types, fast effector reactions, and complex behaviors.

Beauty in the beast – Placozoan biodiversity explored through molluscan predator genomics [PDF]

Ecology and Evolution
The marine animal phylum Placozoa is characterized by a poorly explored cryptic biodiversity combined with very limited knowledge of their ecology.

Evolution of glial cells: a non-bilaterian perspective [PDF]

Neural Development
Nervous systems of bilaterian animals generally consist of two cell types: neurons and glial cells. Despite accumulating data about the many important functions glial cells serve in bilaterian nervous systems, the evolutionary origin of this abundant ...
