How do you not know what a lion looks like when you have a literal lion delivered to you?
I am not a taxidermist (IANAT?), but if I had to guess dead animals look nothing like their living counterparts when given a few days to decay. Taxidermists probably do a ton of work reconstructing things like their faces and that requires knowing what the original face looked like for the model to be accurate. In the works of fiction where I’ve encountered taxidermy it tends to be treated as something of a morbid art.
From Snopes:
An alternative theory holds that the creature’s altered appearance in taxidermy form was intentional and/or the result of the taxidermist’s expectation that the animal would be viewed only from a particular angle:When seen from the side the lion actually has quite a ferocious appearance. In this context, the lion’s bizarre tongue and fake teeth make some kind of sense. Even the close-set position of the eyes seems to have been done in order to make them appear furrowed and angry. Perhaps the taxidermist simply focused too much on side-view images when mounting the pelt, or the lion was (somehow) never intended to be seen from more than one angle.
