Long-term field studies on placozoans (Trichoplax adhaerens), including both substrate sampling and slide sampling, were carried out at a subtidal site near Shirahama, Japan. Samples of natural substrate materials from the field, such as stones, shells, or fragments of coral, were particularly useful for obtaining placozoans. Results from the substrate sampling indicate that placozoans are present year-round at the study site. Large intermittent peaks in the number of animals collected at the… 
Field biology of placozoans (Trichoplax): distribution, diversity, biotic interactions.
Greater expanded distributions for known haplotypes and fresh specimens that include a new haplotype are reported, and the evidence that many more almost certainly await discovery is reviewed, to stimulate a broader search for placozoans and a fuller exploration of their distribution, diversity, and all other aspects of their enigmatic lives.

The results suggest an unknown abundance of placozoans in the Northern Pacific Ocean and further studies on these populations may be essential in solving important biological problems of the phylum.
Putting placozoans on the (phylogeographic) map
A world-wide collecting program greatly increases knowledge of the distribution of specific placozoan haplotypes, more than doubles the number of genetically characterized sites, and reports the first genetic data for isolates from the Eastern Atlantic and Indian Ocean.
Life Strategies in Placozoa
It is shown that regeneration could be a part of the adaptive reproductive strategies in placozoans and a unique model for regenerative biology in general.
Expanding of Life Strategies in Placozoa: Insights From Long-Term Culturing of Trichoplax and Hoilungia
It is hypothesized that spheroid structures represent a component of the innate immune defense response with the involvement of fiber cells and showed that regeneration could be a part of the adaptive reproductive strategies in placozoans and a unique experimental model for regenerative biology.
Caribbean Placozoan Phylogeography
A coarse-resolution presence/absence survey of placozoans in Belize, Bermuda, Grenada, Jamaica, and Panama and a fine-resolution study of the distribution of placzoans in Twin Cays, Belize provide further molecular evidence for species diversity within the Phylum Placozoa.
Mitochondrial Genome of a Japanese Placozoan
The present study determined the mitochondrial genome sequence of a placozoan collected on the coast of Shirahama, Wakayama, Honshu, Japan, and compared it with those of Trichoplax adhaerens from the Red Sea and of three strains from the Caribbean Sea, finding that the ‘Shirahama’ strain most likely represents the H15 lineage.
Highly regulated growth and development of the Ediacara macrofossil Dickinsonia costata
It is shown that development in Dickinsonia costata was surprisingly highly regulated to maintain an ovoid shape via terminal addition and the predictable expansion of modules, suggesting that it does not belong within known animal groups, but that it utilized some of the developmental gene networks of bilaterians.
Global Diversity of the Placozoa
There is great potential and need to erect new taxa and to establish a firm system for this taxonomic tabula rasa within this phylum.


Growth and Behavior of Trichoplax adhaerens: First Record of the Phylum Placozoa in Hawaii
The first record of Trichoplax adhaerens F. Schulze (phylum Placozoa) in Hawaii is reported and some observations on their behavior and growth rates in mixed laboratory culture are described.
Alternative modes of asexual reproduction inTrichoplax adhaerens (Placozoa)
Hollow swarmers are budded off at the dorsal surface of Trichoplax and are covered by dorsal epithelium and there is no indication that the fiber cells included between the epithelia take any part either in morphologenesis or the separation of the bud from the mother animal.
Das radialpolare Differenzierungsmuster bei Trichoplax adhaerens F. E. Schulze (Placozoa) / The Radial Polar Pattern of Differentiation in Trichoplax adhaerens F. E. Schulze (Placozoa)
Fission is involved in the regulation of the quantitative relation between these two kinds of cells and a monstrous modification of the shape and physiologic properties demonstrates a disturbance of these regulations.
Trichoplax adhaerens (Phylum Placozoa) has Cells that React with Antibodies Against the Neuropeptide RFamide
The results of this investigation demonstrate the existence of a specific set of cells which react with antibodies against the neuropeptide family RFamide.

The foundations and goals of conservation biology (and its historical development) awaits elucidation by critical philosophers, and a mature and rigorous refinement will underpin objective knowledge and conservation of organismal biodiversity whilst maintaining biospheric integrity.
