A second species that is sometimes mentioned, <i>Treptoplax reptans</i>, has never been found again after its first and only report and is most likely a fragmented placozoan [2]. With only one species the phylum knows only three taxonomic ranks: Phylum (Placozoa), genus (<i>Trichoplax</i>), and species (<i>T. adhaerens</i>). This situation is soon to change radically. Genetic analyses have suggested that Placozoa harbor at least seven major species clades, which may represent different orders, each with multiple families.\r\n<br>\r\nThe placozoan species database will be updated immediately when a relevant manuscript becomes accepted.
