  ROTIFERA
Rotifera are aquatic animals, but they are particular in choosing their habitate.
Rotifera exhibit two or one eye, which is often made up as an ocellar neck-eye.
Apart from the eye(s), rotifera exhibit sensory cells particularly at the corona, on the back, laterally and on the foot.

  'The Rotifera or Wheel-Animalcules' published by Longmans, Green, And Co. London 1886.
I have decided to show some of the Plates from Volume II but these have intentionally been kept to a modest size, have not been shown in their entirety except for Plate A and some are only a single or group of drawings from more complex plates; none of the images have larger versions attached.
It must be noted that some of the names used for the various Rotifera shown may have changed over the years so although I have used the names given with the Plates these may be incorrect under current classifications.
At the time it was a 'milestone' in the identification, classification and anatomy of Rotifers and shall remain in the history of microscopic study of 'wheel-animalcules' a thorough and compelling reference.

 Introduction to the Rotifera
Rotifers are microscopic aquatic animals of the phylum Rotifera.
Trophi are found in almost all rotifers, and are characteristic organs of the phylum Rotifera.
Phylum Rotifera is divided into three classes: Monogononta, Bdelloidea, and Seisonidea.

Rotifera, as mentioned before, will sometimes excrete a bodily fluid which will stiffen and serve as protection for the animal.
Lophophores all have hollow tentacles that are used to gather food (as are the cilia in the corona in rotifera) and they include organisms such as: mosses (bryozoa) and clam-like animals (brachiopoda).
Rotifera are morely closely related to these animals as they have segmentation, they are worm-like, and when they are developing, they have two bands of cilia around their middle that are used for gathering food and for transportation (Baqai, 2000).

Their name, Rotifera, is Latin for "wheel-bearer" and was given to describe the seemingly circular motion of the corona (ciliated crown) on the top of their heads (Egmond, 1998).
Although rotifera all share these basic characteristics, they are manifested in many different ways, and will be found in different combinations.
Some Rotifera move by means of swimming or crawling while others are sessile (immobile) and attach themselves to a plant or other stationary object.

The Rotifera XI distinguished from all other previous ones in the sense that symposium took full advantage of the internet revolution.
Presentations spanned several themes among which trophic interactions and laboratory experiments on the population and community ecology of rotifers constituted 45% of the total presentations (Table 2).
During the Rotifera XI, almost every aspect of rotifer research – both basic and applied was discussed.

 Rotifer Summary
The 1,500 to 2,000 species in the phylum Rotifera, like other members of the kingdom Animalia, are multicellular, heterotrophic (dependent on other organisms for nutrients), and lack cell walls.
Both asexual reproduction and deterministic cell division are examples of traits that might be considered "primitive" because they are simpler or tend to appear in older taxa.
Yet, by examining a phylum like Rotifera and understanding its evolutionary history, we realize that there are situations in which apparently "primitive" traits replace "advanced" ones.

The phylum Rotifera includes about 1,800 described species, of which approximately 50 are marine.
The remaining species are primarily freshwater, although some live in damp soils, or in the water film on some mosses (Brusca and Brusca, 1990).

Major issues include phylogeny and evolution, genetics and molecular ecology, new aspects of rotifer anatomy through the application of confocal laser-scanning microscopy, anhydrobiosis, long-term studies in lakes and rivers, population dynamics and community ecology, trophic relationships between copepods and rotifers, alongside biodiversity studies based on classical taxonomic concepts and molecular approaches.

The Rotifera collection of the Academy of Natural Sciences presently consists of 1,969 microscope slides containing complete specimens or trophi preparations, 135 of which contain type specimens.
At that time F.J. Myers was a research fellow of the Academy, where he was involved in studies on the microfauna of freshwater habitats on the Pocono Plateau (Pennsylvania: Myers, 1940, 1942).
Apparently, he also examined Rotifera from some New Jersey localities he had published about previously (Myers, 1936).
