Extract from Fantastic Beasts and Where to Find Them

By J.K. Rowling

The Knarl (northern Europe and America) is usually mistaken for a hedgehog by Muggles. The two species are indeed indistinguishable except for one important behavioural difference: if food is left out in the garden for a hedgehog, it will accept and enjoy the gift; if food is offered to a Knarl, on the other hand, it will assume that the householder is attempting to lure it into a trap and will savage that householder’s garden plants or garden ornaments.
