Dendrogramma
''Dendrogramma'' is a genus consisting of two species, ''D. enigmatica'' and ''D. discoides'', identified in 2014 from a collection of specimens gathered in 1986. The two species, which are small ocean-dwelling organisms, have been placed in the animal kingdom, but have not been definitively assigned to any existing phylum.〔 The two species are the only known members of the family Dendrogrammatidae.〔
In 2015, the International Institute for Species Exploration names it as one of the "Top 10 New Species" for new species discovered in 2014.〔(【引用サイトリンク】url=http://www.esf.edu/top10/ )〕
==Discovery==
The ''Dendrogramma'' specimens were collected off the south-east coast of Australia during a scientific expedition in 1986. They were collected at water depths of and on the continental slope near Tasmania, using a sled that was dragged over the sea floor to collect bottom-dwelling animals.〔 The researchers were immediately struck by the unusual characteristics of the 18 specimens they collected. These were preserved in formaldehyde, and later in ethanol, for further study.
On returning to the sample site in 1988, they were unable to find any further specimens. It was not until 2014 that they published the discovery. Jean Just of the University of Copenhagen, who carried out the trawling in 1986, has explained the long delay before publication in terms of the extraordinary nature of the discovery: "Once you think you have something really extraordinary, it takes a long time to study, read, consult left, right and centre, and convince yourself that you’ve really stumbled across something special."〔
