Instruction: What are magical creatures?

Response: Magical creatures are an aspect of the fictional Wizarding World contained in the Harry Potter series and connected media originally created by British author J. K. Rowling. Throughout the seven main books of the series, Harry and his friends encounter many of these creatures on their adventures in Hogwarts, the Forbidden Forest, or other locations throughout the Wizarding World. In addition, students learn to take care of creatures such as hippogriffs and unicorns in the Care of Magical Creatures class at Hogwarts. Rowling has also written Fantastic Beasts and Where to Find Them, a guide to the magical beasts found in the series, and based on the fictional textbook of the same name written by Newt Scamander and used by students at Hogwarts.
Some creatures in the series are ordinary animals that may be imbued with magical properties or possess certain magical abilities. Owls, for example, deliver mail and have the ability to find the recipient regardless of their location. Other animals such as cats, dogs, frogs, toads, rats and mice do not necessarily have magical abilities.
