Magizoology is the study of magical creatures. Wizards and witches in this field are referred to as Magizoologists. The most famous magizoologist was Newt Scamander, author of Fantastic Beasts and Where to Find Them. Luna Lovegood was also a Magizoologist in her later career, as was Luna's husband, Rolf Scamander, Newt Scamander's grandson. Rubeus Hagrid could be considered a Magizoologist, since he was the Care of Magical Creatures professor at Hogwarts, as would his predecessor, Silvanus Kettleburn.
The Department for the Regulation and Control of Magical Creatures gives classifications to all known beasts, beings, and spirits. These offer an at-a-glance guide to the perceived dangerousness of a creature.

Zoology is the branch of biology that focuses on the structure, function, behaviour, and evolution of animals. So, Magizoology is a combination of the word "magic" and "zoology".
Behind the scenes
A real world field of study related to Magizoology is Cryptozoology, the study of hidden animals that were believed to be extinct, yet some people catched a glimpse of their existence in real-life.
