Obligate parasitoid nanoflagellate that preys on marine diatoms. Cell with apical “nose”, two medianly inserted flagella; feeds by means of a trophosome; dividing auxosomes are globular and covered by a mucilaginous coat, frequently with adhering bacteria; movement gliding rather than swimming, feeds on the diatoms Rhizosolenia imbricata, R. setigera, Leptocylindrus danicus, Guinardia delicatula and G. flaccida.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
