Trans-Species Transformation

Trans-Species Transformation was a sub-type of transformation magic in which one organism is transformed into something a different species.

It is probable that Cross-Species Switches are an example of Trans-Species Transformation, due to the similarity in their names. If this is so, then Transforming Spells must be adapted to perform Trans-Species Transformation.

The periodical Transfiguration Today provided some information on this branch of magic, as Albus Dumbledore submitted a paper on it to the periodical.
