Coordinated Feeding Behavior in Trichoplax, an Animal without Synapses. [PDF]
PLoS ONE, 2015 Trichoplax is a small disk-shaped marine metazoan that adheres to substrates and locomotes by ciliary gliding. Despite having only six cell types and lacking synapses Trichoplax coordinates a complex sequence of behaviors culminating in external ...

Social Feeding Behavior of Trichoplax adhaerens [PDF]
Frontiers in Ecology and Evolution, 2019 Animals have evolved different foraging strategies in which some animals forage independently and others forage in groups. The evolution of social feeding does not necessarily require cooperation, social feeding can be a beneficial individual-level ...

Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux. [PDF]
J Exp Zool B Mol Dev EvolEpithelia 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.

Metabolic and Chaperone Gene Loss Marks the Origin of Animals: Evidence for Hsp104 and Hsp78 Sharing Mitochondrial Clients [PDF]
, 2015 The evolution of animals involved acquisition of an emergent gene repertoire for gastrulation. Whether loss of genes also co-evolved with this developmental reprogramming has not yet been addressed.

Differentiation of Crystal Cells, Gravity-Sensing Cells in the Placozoan Trichoplax adhaerens
Journal of Marine Science and Engineering, 2021 Trichoplax adhaerens are simple animals with no nervous system, muscles or body axis. Nevertheless, Trichoplax demonstrate complex behaviors, including responses to the direction of the gravity vector.

The early ANTP gene repertoire: insights from the placozoan genome. [PDF]
PLoS ONE, 2008 The evolution of ANTP genes in the Metazoa has been the subject of conflicting hypotheses derived from full or partial gene sequences and genomic organization in higher animals.

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 ...

The cobalamin processing enzyme of Trichoplax adhaerens. [PDF]
J Biol ChemCobalamin (Cbl) is an essential cofactor for methionine synthase and methylmalonyl-CoA mutase, but it must first undergo chemical processing for utilization in animals. In humans, this processing comprises β-axial ligand cleavage and Cbl reduction and is performed by the enzyme MMACHC (HsCblC).

Animal Evolution: Trichoplax, Trees, and Taxonomic Turmoil [PDF]
Current Biology, 2008 The genome sequence of Trichoplax adhaerens, the founding member of the enigmatic animal phylum Placozoa, has revealed that a surprising level of genetic complexity underlies its extremely simple body plan, indicating either that placozoans are secondarily simple or that there is an undiscovered morphologically complex life stage.
