The Microarbre replaced its ancestor, the Microdendron. These cells still live on the sea floor of the coasts or on the floor of underwater caves and make micro forests, but now they have developed micro tentacles and with them they move organic material to their "mouths". Now the microarbre can live inside dark areas too.

None found. Note that this does not necessarily mean it has no living relatives at all, but that, assuming all taxonomy is filled in, its entire phylum is extinct; any relatives it does have likely do not resemble it.
