She didn't choose to violate genre conventions. She doesn't read fantasy in the first place, and Harry Potter wasn't intended as a (high) fantasy.
In an interview with The New York Times, J. K. Rowling said the following:
Any literary genre you simply can’t be bothered with?
“Can’t be bothered with” isn’t a phrase I’d use, because my reading tastes are ...
The "Werewolves" in the Forest are Actually Highly Intelligent Regular Wolves
This is from the Pottermore entry on werewolves:
One curious feature of the condition is that if two werewolves meet
and mate at the full moon (a highly unlikely contingency which is
known to have occurred only twice) the result of the mating will be
wolf cubs which ...
Hogwarts is their home. The kids are (mostly) protected by being told to keep away from the animals.
Many of the creatures in question considered Hogwarts to be their home, just as much as any of the children did.
"What are you doing in our Forest?" bellowed the hard-faced grey centaur Harry and Hermione had seen on their last trip into the Forest. "Why ...
Yes, the dodo.
In the Harry Potter universe, the small flightless birds are actually magical creatures called Diricawls that can disappear at will when humans approach. Muggles assume they've hunted them to extinction, and the magical community declines to tell them the truth because of the way it's sparked conservation efforts.
Interestingly, Muggles were ...
Dragons in Harry Potter are indeed powerful.
Though it’s true that dragons were used in one of the tasks of the Triwizard Tournament competed in by schoolchildren, dragons were shown to be powerful creatures. The task wasn’t actually to defeat a dragon, just to retrieve an egg guarded by one. To defeat a dragon, Sirius Black says would need about six ...
I would say no.
We have two canon instances of a boggart taking the form of a deadly creature.
The first is a banshee, which materialises as Seamus’s fear in the first class with the boggart.
Where the mummy had been was a woman with floorlength black hair and a skeletal, green-tinged face – a banshee. She opened her mouth wide and an unearthly sound ...
I would say yes.
Three pieces of supporting evidence:
Using Thestrals for transport is a serious breach of the Statute of Secrecy.
From the first WOMBAT (transcript on HP Lexicon), if we assume that it isn’t a trick question, then we learn that Thestrals can’t be used for transport:
Which of the following unorthodox means of transportation is ...
You need to bow again.
Harry bowed to Buckbeak in the lessons:
Harry didn't much feel like exposing the back of his neck to Buckbeak, but he did as he was told. He gave a short bow and then looked up.
Harry Potter and the Prisoner of Azkaban, chapter 6
but when he goes back in time he has to bow again. Remember, this is all chronologically after that ...
It doesn’t seem to be a requirement to bow, just highly advised.
In Fantastic Beasts and Where to Find Them, Newt writes that bowing to the Hippogriff shows good intentions, but he doesn’t say it’s an absolute requirement to tame or ride on one. It’s likely that by not bowing, the person who doesn’t risks being attacked like Draco if the Hippogriff doesn’t ...
Let me quote J. K. Rowling's answer from her old website at
Why could Harry see the Thestrals 'Order of the Phoenix'? Shouldn't he have been able to see them much earlier, because he saw his parents/Quirrell/Cedric die?
I’ve been asked this a lot. Harry ...
Danger is part and parcel of a Hogwarts education
Hagrid may deal with dangerous creatures, and believe them to be far less dangerous than they actually are, but in bringing them to lessons, he is very much in accord with the general tenor of lessons at Hogwarts.
In Herbology, students deal with Mandrakes, whose cry, when mature, will kill those ...
An answer comes from a Pottermore update which describes the history of the Chamber of Secrets (transcript), along with some speculation of my own.
Here’s the relevant passage:
(In spoiler text for those who want to work through Pottermore themselves; spoilers in the discussion below.)
So here are my answers to your specific questions:
Indoor plumbing in ...
Not specifically, but we know from a Bloomsbury Live Chat with JKR that Luna spent her entire professional life looking for one (with her husband, the noted Magiczoologist Rolf Scamander, grandson of Newt) and never found one. Sadly, nargles also appear to be fictional.
J.K. Rowling: Luna became a very famous wizarding naturalist who discovered and ...
Some do, but some also infest Muggles.
Certain magical pests are either created by or attracted to magic, so therefore affect only wizard dwellings. Other magical pests do indeed infest and affect Muggles, but they are simply ignorant to the source of their troubles.
Pests that only exist around magic:
Ashwinders are created when magical fires ...
The Cornish pixies make their second appearance in the Room of
Requirement in Harry Potter and the Deathly Hallows – Part 2.
Behind the scenes: Cornish pixies
These are, of course, the same kind of pixies (possibly even the very same pixies given that Lockhart would have had no further need for them) that Harry valiantly fought against in ...
There are no werewolves in the Forest. Hagrid was just giving a quick, factual answer. He might also have been teasing Malfoy.
I think it's correct to say that there were no werewolves in the Forest for the reasons stated in the question. Primarily, it would've been dangerous for the students; I think we can conclude that Dumbledore was aware that students ...
Those creatures are Matagots, spirit familiars that resemble cats.
Those cat-like creatures are Matagots, as Newt says when he sees them in the French Ministry.
At that moment, MELUSINE enters the records room surrounded by growling Matagots.
(scared) What kind of cats are those?
These aren’t cats, they’re ...
The non-human creatures that use magic aren’t called wizards.
There are some non-human creatures that can do magic, like goblins and house-elves, but those beings aren’t called wizards - wizards have to be human, at least partially. Griphook, a goblin, makes a clear distinction between wizards and other magical beings (including goblins like him).
This is 'Egg Creature'.
Apologies if that seems like an anti-climax but, based on a discussion with the filmmakers, I think that's the best answer we're going to get.
Firstly, if it seems that this isn't a creature that was mentioned in the books, that's because it isn't. That was my first impression as a Harry Potter gold badge holder and I was unable to ...
According to JKR, gnomes are only found in the homes of wizards. No specific explanation is given as to why this is.
Q. Why are the gnomes bad? What do they do?
JKR: Gnomes eat the roots of your plants, and make little heaps of earth, like moles do. They are also a bit of a giveaway that
wizards live in a house.
Scholastic: Interview With J. K....
Unsurprisingly, most of the White Walker (The Others) abilities revolve around ice and cold. I am going to draw on some back story from the A Song of Ice and Fire novels, but only where it is relevant to what we also see in the Game of Thrones show-verse.
Create swords and other items from ice (seen in show):

The official info from Fantastic Beasts and Where to Find Them mentions that they enjoy 'large prey'
The Acromantula is a monstrous eight-eyed spider capable of human
speech. It originated in Borneo, where it inhabits dense jungle. Its
distinctive features include the thick black hair that covers its
body; its legspan, which may reach up to fifteen ...
Salamanders are mentioned in Fantastic Beasts and Where to Find Them as being magical in nature. Their properties don't, however, match those of muggle salamanders.
The salamander is a small fire-dwelling lizard that feeds on flame. Brilliant white, it appears blue or scarlet depending upon the heat of the fire in which it makes its appearance.
There is no cure for someone who's already become a werewolf.
This passage states that there's no way to cure a werewolf, not necessarily that there's no way to cure a werewolf bite.
Humans turn into werewolves only when bitten. There is no known cure, though recent developments in potion-making have to a great extent alleviated the worst symptoms. ...
The answer is in the details of the quote.
You cannot destroy Dementors
There is a great deal of difference between being able to destroy a Dementor, and them never dying.
This leads into speculative theory, but I believe the idea is that by limiting the conditions in which they thrive, you can starve the dementors, and cause their numbers to diminish....
We have detailed descriptions of all three in canon. They appear similar on the surface, but they don't seem to have much in common (other than a propensity for annoying living humans).
From Fantastic Beasts and Where to Find Them:
The Ghoul, though ugly, is not a particularly dangerous creature. It resembles a somewhat slimy, buck-toothed ogre ...
Phoenixes and Diricawls can vanish and reappear at will, which may or may not count as Apparition. Both of these are mentioned in the Fantastic Beasts and Where to Find Them book. Professor Dumbledore's Phoenix Fawkes is even shown to vanish together with the Professor in Harry Potter and the Order of the Phoenix. I don't have the book at hand, but I don'...
Well, first of all, quite a number of creatures are omitted from the version of Fantastic Beasts published by J.K. Rowling. No thunderbird, no swooping evil, and so forth. I suppose one could argue that they were redacted, but Rowling has mentioned (on Pottermore) various other creatures that would seem to meet the criteria for “beasts” as laid out in ...
Word of God answer from Rowling: "An Obscurus isn't a creature"
Rowling responded to a fan's speculation on twitter, saying that Obscurus would not be featured in the updated edition of Fantastic Beasts and Where to Find Them, because it "isn't a creature".
The new edition of Fantastic Beasts and Where To Find Them will feature a foreword ...
