"Morph" doesn't mean "shape-change", although little over a decade of morphing technology seems to created that association in the public mind. It simply means "shape", usally of living things, as in the scientific term morphology (coined by Goethe, by the way) to describe the anatomical structure of organisms. The scientific names for several families of plants and animals (and in a few cases, genuses) use the suffix-morphs to denote that they were at least initially classified on the basis of their common shape; when used as a suffix in species, it usually indicates a strong or startling resemblance to a completely unrelated species.
