Spherical forms ofTrichoplax adhaerens (Placozoa)
Zoomorphology, 1990Two types of spherical forms of this normally flattened organism appear sporadically in our cultures. Hollow spheres have an outer wall of flagellated ventral epithelium. The large fiber cells protrude into the central cavity which can include a closed compartment of flagellated dorsal epithelium.

On the genetic uniformity of the genus Trichoplax (Placozoa)
Russian Journal of Genetics, 2004Fragments of the nuclear and mitochondrial genes for the large-subunit rRNA were compared for Trichoplax sp. and T. adhaerens. High similarity was observed for their sequences, suggesting that different Trichoplax isolates belong to one species.

Placozoans are morphologically the simplest free-living animals. They represent a unique window of opportunities to understand both the origin of the animal organization and the rules of life for the system and synthetic biology of the future. However, despite more than 100 years of their investigations, we know little about their organization, natural

PREFAZIONE Perché un nuovo testo di Zoologia? La risposta sta innanzitutto nella quantità di nuove informazioni, derivanti dagli studi basati sull’uso di approcci cladistici e molecolari, che hanno rivoluzionato le nostre conoscenze sui rapporti filogenetici tra gli animali, soprattutto invertebrati.

Alternative modes of asexual reproduction inTrichoplax adhaerens (Placozoa)
Zoomorphology, 1991Hollow swarmers are budded off at the dorsal surface ofTrichoplax and are covered by dorsal epithelium. Their inner cavity is lined with the flagellated cells of the ventral epithelium. 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 ...

The phylogeography of the Placozoa suggests a taxon-rich phylum in tropical and subtropical waters
Molecular Ecology, 2010Placozoa has been a key phylum for understanding early metazoan evolution. Yet this phylum is officially monotypic and with respect to its general biology and ecology has remained widely unknown. Worldwide sampling and sequencing of the mitochondrial large ribosomal subunit (16S) reveals a cosmopolitan distribution in tropical and subtropical waters of
