The demiguise is known for two very powerful properties: invisibility and predicting the future. Only well-trained witches and wizards can see them; one must engage in something completely unpredictable to find the ape-like creatures, otherwise they'll predict their capture. Fun fact: it's possible demiguise hair was used to make one of Harry Potter's most prized possessions: his invisibility cloak. Demiguise hair pelts can be woven into them.
