Identificación y revisión bibliográfica del antecesor de Eumetazoa: "Trichoplax adhaerens" [PDF]
, 2020 The phylum placozoa is a group of primitive animals with great evolutionary and pharmacological interest. It is represented by a few genus, when Trichoplax and its representative species T. adhaerens are most studied.

BMC Genomics, 2012 Background MicroRNAs play a vital role in the regulation of gene expression and have been identified in every animal with a sequenced genome examined thus far, except for the placozoan Trichoplax. The genomic repertoires of metazoan microRNAs have become

Deep RNA sequencing reveals the smallest known mitochondrial micro exon in animals: The placozoan cox1 single base pair exon. [PDF]
PLoS ONE, 2017 The phylum Placozoa holds a key position for our understanding of the evolution of mitochondrial genomes in Metazoa. Placozoans possess large mitochondrial genomes which harbor several remarkable characteristics such as a fragmented cox1 gene and trans ...

Binary fission in Trichoplax is orthogonal to the subsequent division plane.
Mechanisms of Development, 2020 Asexual reproduction in Trichoplax occurs mainly by binary fission and occasionally by the budding of epithelial spheres called "swarmers". The process that leads to binary fission and the mechanisms involved in this segregation are practically unknown ...

Trichoplax feeding on Rhodamonas salina microalgae.
, 2015 Algae appear as tiny red specks on the substrate due to their content of fluorescent phycoerythrin. At 8 to 24 sec groups of algae under the paused Trichoplax precipitously release their contents apparent as contiguous domains of bright red phycoerythrin.

Support for a clade of Placozoa and Cnidaria in genes with minimal compositional bias
eLife, 2018 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 ...

Eating and Cognition in Two Animals without Neurons: Sponges and Trichoplax
Biological TheoryEating is a fundamental behavior in which all organisms must engage in order to procure the material and energy from their environment that they need to maintain themselves.

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Concatenated analysis sheds light on early metazoan evolution and fuels a modern "urmetazoon" hypothesis. [PDF]
PLoS Biology, 2009 For more than a century, the origin of metazoan animals has been debated. One aspect of this debate has been centered on what the hypothetical "urmetazoon" bauplan might have been.

Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance Trichoplax is a disk-shaped marine animal whose body plan and lifestyle could be similar to those of the Precambrian ancestor of many animals on earth today. It has only six cell types and no nervous system.
