Despite being composed of just a single cell, this organism shows complex behavior. Those still suffering from an inferiority complex should consult the papers by Gao et al or Zhang et al’s  “Insights into the phylogeny of systematically controversial haptorian ciliates based on multigene analyses” and admire the beautiful, multicolored taxonomic trees and RNA maps. It can extend its "neck" quite a bit and pokes around. – MC. Careful classifications based on overall anatomy, ciliary structure, or the gonadal morphology of worms have been turned on their heads. marina Kahl, 1933 (ref. When you emerge, you will feel better with the knowledge that much smarter people than you struggle with taxonomy and are busy messing up everything that you THINK you know, so why bother?

Protozoa (also protozoan, plural protozoans) is an informal term for a group of single-celled eukaryotes, either free-living or parasitic, which feed on organic matter such as other microorganisms or organic tissues and debris. Lacrymaria is one of the litostomate ciliates, tiny creatures with unique, highly-specialized mouth structures. Dioni, W.  “An Annotated Key for Species of the Family Stentoridae and Two Related Families:  An Excursion Through the Taxonomic Maze.”  http://www.microscopy-uk.org.uk/mag/indexmag.html?http://www.microscopy-uk.org.uk/mag/artnov04/wdstentor.html.

I often tell students, “If you are confused, and think that nothing about this subject makes sense, it may be that you understand the topic.”  If you are confused, it may be that the subject is confusing rather than that you are stupid. The exact characteristics of this class have to date been poorly characterized;  Gao notes, “…The class Litostomatea has been traditionally rather poorly defined as having an apically positioned cytostome, uniform somatic ciliation and a non-distinct oral apparatus…”  Unlike many protozoa, where ingestion can occur at any site on the membrane, this group of organisms sports an apical cytostome or “mouth”.
