With the head of a human on the body of a lion, the sphinx is a highly intelligent creature that specialises in puzzles and riddles and as a result are often use by witches and wizards as guards for secret hideaways and valuable objects. They are classed as ‘beasts’ despite their intelligence due to their potentially dangerous natures. One sphinx was used as part of the third task in the Triwizard Tournament, held at Hogwarts.
