A pencil sketch of a bdelloid rotifer (species Philodina rosea
) which I drew for my Spring 2010 drawing class. The weekly outside assignment was a great excuse for me to pick and choose animals I'd always wanted an excuse to draw, and rotifers are at the top of my list. Rotifers are fascinating, somewhat cute, funny to watch, and utterly unique, and they occupy their own phylum in the animal kingdom, yet virtually no one outside of certain biological sub-disciplines knows they exist. I find rotifers' obscurity lamentable, so as a tribute to their awesomeness, I drew one to the best of my ability.
I used multiple source images (both illustrations and photos) to get a grasp on the specifics of rotifer anatomy, but the sketch is primarily based on one excellent rotifer-under-the-microscope photograph where even the eyespots are clearly visible. That photograph, and many more of the best rotifer images on the web, can be found here
