micrograph of the rotifer Macrochaetus

The Academy of Natural Sciences of Drexel University houses the world's most comprehensive collection of rotifers on microslides. The collection is comprised of 1,935 slides covering 744 taxa from 34 countries. Some 96% of the slides are in excellent condition, largely due to the widespread use of pure glycerine as a mounting medium. A total of 1228 images belonging to 730 taxa from the collection are included in the online catalog. A CD-ROM edition of the catalog, A Magnificent Diversity: The Frank J Myers Rotifera Collection can be purchased online via Diane Publishing Co.
