Global Habitat Suitability and Ecological Niche Separation in the Phylum Placozoa. [PDF]
The enigmatic placozoans, which hold a key position in the metazoan Tree of Life, have attracted substantial attention in many areas of biological and biomedical research.

Hidden cell diversity in Placozoa: ultrastructural insights from Hoilungia hongkongensis [PDF]
AbstractFrom a morphological point of view, placozoans are among the most simple free-living animals. This enigmatic phylum is critical for our understanding of the evolution of animals and their cell types. Their millimeter-sized, disc-like bodies consist of only three cell layers that are shaped by roughly six major cell types. Placozoans lack muscle

Phylogenetic position of Placozoa based on large subunit (LSU) and small subunit (SSU) rRNA genes [PDF]
The phylum Placozoa, represented by its single species Trichoplax adhaerens, has always been considered one of the most basal animal clades due to its low morphological complexity.

Molecular signatures for sex in the Placozoa [PDF]
Placozoans, the simplest free-living animals, have never been observed to reproduce sexually. Here, we describe molecular evidence for sexual reproduction within one clade of the Placozoa. In a population sample of 10 individuals, within-individual and overall nucleotide diversity were similar to each other and consistent with levels observed in ...

Expansion microscopy in Placozoa: improving resolution and preservation of fragile samples during marine expedition [PDF]
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.

Global diversity of the Placozoa.
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 ...

Placozoa Are Not Derived Cnidarians: Evidence from Molecular Morphology [PDF]
The phylum Placozoa is represented by a single known species, Trichoplax adhaerens, a tiny marine organism that represents the most simple metazoan bauplan. Because of the latter, placozoans were originally considered the most basal metazoan phylum.

Studying Placozoa WBR in the Simplest Metazoan Animal, Trichoplax adhaerens. [PDF]
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.

Placozoa and Cnidaria are sister taxa [PDF]
AbstractThe 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.
