In Harry Potter, there are many instances of fantastic beasts. What makes those beasts magic? Why is a Flesh-eating slug magic, for example, but not a Venus Flytrap?

Not a dupe of How does a Flobberworm differ from a regular worm? because here I'm looking for an inherent nature (such as what makes magical things magical) but there I'm searching for any physical characteristic.

    Because all of the magical beasts are.......erm.....magical.

    Most of them are obvious-- creatures with magical abilities (thestrals), or whose existence normal physics can't explain (hippogriffs). But +1 for the corner cases, like your flesh-eating slug example. Apr 17, 2018 at 18:26
