Some of the identifying morphologic characteristics include pairs of thread-like flagella that facilitate motility, and a ventolateral flange that appears as a “ruffle” around the anterior portion of the organism. Pairs of flagella seen here include an anterior, posterior-lateral, and caudal pairs.

    This photo, I think, is credited to the late Stan Erlandsen from the U of Minnesota. Of course, it wasn't color enhanced back then. I was lucky enough to work as a grad student with Dr. Erlandsen. He took many great pictures of Giardia along with Dr. Feely.
