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 ...

Cells containing aragonite crystals mediate responses to gravity in Trichoplax adhaerens (Placozoa), an animal lacking neurons and synapses [PDF]
PLoS ONE, 2018 Trichoplax adhaerens has only six cell types. The function as well as the structure of crystal cells, the least numerous cell type, presented an enigma. Crystal cells are arrayed around the perimeter of the animal and each contains a birefringent crystal.

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.

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.

Amino acids integrate behaviors in nerveless placozoans [PDF]
Frontiers in Neuroscience, 2023 Placozoans are the simplest known free-living animals without recognized neurons and muscles but a complex behavioral repertoire. However, mechanisms and cellular bases of behavioral coordination are unknown.

An ancient lysozyme in placozoans participates in acidic extracellular digestion [PDF]
Communications BiologyLysozymes are an essential part of immunity and nutrition in metazoans, degrading bacterial cell walls via the hydrolysis of peptidoglycan. Although various lysozymes have been reported for higher animals, the origin of animal lysozymes remains elusive ...

Non-coding RNA annotation of the genome of Trichoplax adhaerens [PDF]
Nucleic Acids Research, 2009 A detailed annotation of non-protein coding RNAs is typically missing in initial releases of newly sequenced genomes. Here we report on a comprehensive ncRNA annotation of the genome of Trichoplax adhaerens, the presumably most basal metazoan whose genome has been published to-date.
