Dendrogramma
Dendrogramma enigmatica is a species of siphonophore, the only one in its genus. It has been first described in 2014 on the basis of its morphology from a collection of specimens gathered in 1986. Its taxonomic affinity among animals was then unclear, but RNA from new specimens in 2016 allowed it to be identified as a siphonophore by barcoding and phylogenomics. The specimens are presumed to represent parts (bracts) of an entire siphonophore that has not been identified yet.

Известен по фрагментам, найденным на дне океана к югу и юго-востоку от Австралии[1][2]. Первые экземпляры Dendrogramma были найдены в 1986 году, но описаны лишь в 2014. Определить её систематическое положение тогда не удалось даже с точностью до типа, и загадочное животное получило широкую известность. Находка вошла в «Десять самых замечательных видов» года; высказывалось предположение, что она близка к организмам эдиакарской биоты, существовавшей около 600 млн лет назад[3].

== Discovery == The first 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.
