Hi , does anyone know what is this microorganism?

 

It is a slug like organism which swims in the water and may also walk on algae

 

It has two fan-like structures on its head which spins to catch food particles.

 

The picture provided is at 100X under my microscope.

Can't capture full body because it keeps on moving around.

If it fan like structure keep spinning and that structure is made by cillia, it could be rotifers, the most smaller multicellular animals in the world. But i suggest it only from your description, from picture it is very hard to say what it is.

I agree, it sounds very much like a rotifer, from the description.

Thanks for identifying the following organism.

A friend of mine suggested the types of rotifers to me so I did some further research and concluded that it’s a Philodina rotifer.

 

More pictures and information can be seen in detail from the following link:

Here is an anatomy of this organism.
