More recently, giant spiders have featured in books such as the 1998 fantasy novel "Harry Potter and the Chamber of Secrets" by J. K. Rowling. This book was later followed by a motion picture of the same name, using the giant spider Aragog from the novel as a supporting character and pet of grounds keeper, Hagrid. In "Fantastic Beasts and Where to Find Them", a book about many of the creatures within the Wizarding World, these giant spiders are also known as Acromantulas.
