The previous Mystery Micrograph was of the surface of Blepharisma, a characteristically pink ciliate. You can see rows of the pigment granules responsible for the unusual colour. Not clearly visible throughout most of the image (only on the top side) are rows of cilia that are interspersed between the pigment granule rows (about every 5-7 rows are cilia). It's a pretty cell to look at !

Now it's time for another. To make this more 'fun', I'll leave out the scalebar for now. (Mwahaha!)

What is this, and whom is it a part of?
