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 ...

Review: The evolution of peptidergic signaling in Cnidaria and Placozoa, including a comparison with Bilateria

Frontiers in Endocrinology, 2022
Bilateria have bilateral symmetry and are subdivided into Deuterostomia (animals like vertebrates) and Protostomia (animals like insects and mollusks).

Phylogenetic position of Placozoa based on large subunit (LSU) and small subunit (SSU) rRNA genes

Genetics and Molecular Biology, 2007
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.

Animal Evolution: The Enigmatic Phylum Placozoa Revisited [PDF]

Current Biology, 2005
A recent report of high levels of genetic variation between strains of Trichoplax adhaerens challenges the traditional view that the phylum Placozoa comprises only one species. At the morphological level, placozoans are amongst the simplest extant animals, but molecular evidence suggests that they may have more complex origins.

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.

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

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.

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.

Placozoa – no longer a phylum of one [PDF]

Current Biology, 2004
AbstractMore than a century ago, the simplest of all metazoans was discovered and described as Trichoplax adhaerens[1]. These tiny, flattened animals lack symmetry, mouth, gut, nervous system, and extra-cellular matrix and constitute the apparently monotypic phylum Placozoa.

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.
