The Vrolik Museum is housed in the Medical Center of the University of Amsterdam and contains nearly 500 animal and human specimens on display. Every specimen has some anatomical abnormality; congenital deformities that rendered the majority unable to survive past their birth. The various warped forms, usually floating in preservative fluid, are astoundingly varied. At the museum, one can see microcephalics, conjoined twins, ancephalics, dysmeliacs, and all the rest. The study of such developmental defects is called teratology, which literally means "the study of monsters."
Still, this is no mere freakshow. This collection (largely amassed by the father and son team of Professors Girard and Willem Vrolik) has supplied biologists and medical scientists key information about the morphological development.
