Strangely, though perhaps 50% of all species live a parasitic lifestyle, parasitism is infrequently and superficially covered in undergraduate biology curriculum.  Parasites are inherently fascinating  to the biologist and layman alike, and provide an opportunity to teach foundational biology concepts while maintaining student interest.  Here is a place where we can share resources that feature parasites, for the array of classes in biology- from strict parasitology courses to introductory biology.
