Nymphadora Tonks is a fictional character in the Harry Potter book series written by J. K. Rowling. Tonks, as she is known, is the daughter of Andromeda Black and Ted Tonks. She is a Half-Blood, but both of her parents are actually magical.
It is never revealed if Metamorphmagi can take the full form of an animal, and Tonks simply describes the ability as being able to change her appearance. Also, a Metamorphmagus is born, not made; it is not a skill that can be learned. There also seems to be a degree of heritability, as both Nymphadora Tonks and her son, Teddy Lupin, were Metamorphmagi, although both of Tonks' parents, Andromeda and Ted, were not.
