General Notes
Thestrals are an elusive, carnivorous species of winged horse, visible only to those who have witnessed and embraced a death,and described as having "blank, white, shining eyes," a "dragonish face," "long, black manes," "great leathery wings," and the "skeletal body of a great, black, winged horse"; also described by Hagrid as "dead clever an' useful", and also by Harry as "reptilian". They have acquired an undeserved reputation as omens of evil.
