I would just like to note that Tolkien was probably referencing World War one rather than World War two as he was a WWI vet.(Though it was probably some of both.)
http://en.wikipedia.org/wiki/Tolkien#World_War_I
Tolkien was referencing WWII in LOTR quite obviously, although he always denied doing this. Silmarillion does seem to have some minor hints at WWI.
Again, it depends what you mean by "referencing"; Tolkien denied it was an
allegory, not that he was inspired by real life. The problem with
allegory, specifically, is twofold (and if you dig around on the net I'm sure you can find Tolkien's own take on these from his letters, I just want to make the point here):
1) You start arguing about how "Middle Earth" fits into European geography (despite originating in Norse Mythology as a semi-theological name for the realm of mortals 'twixt Valhalla/paradise and Hell or whatever the Norse thought of as the realm of the giants and other enemies of good, but more on filtering in a moment) and ignoring how things like the creation of the world or like the Ring never being aquired and used by Gondor to end the war
don't fit into the WWI/WWII filter or the industrialism vs pastoralism filter or even the fact that you can really pick any filter you want and make it work. I could say that Tolkien's work exhibits a strong hippie bent -- I just have to ignore where it considers civilization in general a dignified thing (the entire conflict winds up restoring an ancient kingdom and all the heroes like that; the ancient kingdoms that have fallen are considered to have made their mistakes but the world is considered the worse for their fall through those mistakes; etc.) and looks approvingly in principle upon bathing! Even in the things that you argue are "obvious" the fit really isn't that tight (and this is equally obvious): for America to have been the "True West" that stays out of wars in Middle Earth, America would have to be far more an idealized paradisical kingdom than any American has ever dreamed of -- and we've had our city-on-a-hill folks pressing "manifest destiny" (a code word for imperialism justified by our superior virtue -- same thing most imperialism is justified by) from before splitting with England -- all of which makes no sense coming from a traditional-leaning English Catholic like Tolkien. The alternative geography-matching filter is that America is Numenor; but Numenor is not a new kingdom, it's the ancient kingdom that fell and whose colonies split off into Gondor and whatever the northern branch Aragorn comes from is (this is why I begin discussions of Tolkien with a note that I'm familiar with much more than LotR but am due for a rereading, har har). Now, it's all very well and good to discuss interesting similarities here and there, to argue their differences, and to try to see what insight can be gleaned from them; but the problem with allegory is that it
requires these arguments be the most relevant thing, such that...
2) You miss out on entire things in Tolkien's work that have nothing to do with the allegory one way or the other. For a trivial, fun example, balrogs -- you can have entire debates about whether they can fly, but that will never come up in an allegorical filter unless the filter happens to have a place for balrogs in which their flight or lack thereof is relevant (even if you look at Tolkien's religion and make the mistake of comparing elves with angels and big beasties with devils, that wouldn't really follow -- devils aren't supposed to be of this plane of existence, and "flight" is about as applicable outside it as "shaving one's mustachios"). For a bigger example, it's possible to write entire books about his philosophy of subcreation reflected in The Silmarillion and elaborated upon in some of his letters. I know someone who wrote a thesis on it. There are bits of it that take from medieval philosophy, there are bits of how he reflects it in the Silmarillion that explain why Sauron could pour his strength out into the Ring... are we really going to argue about geography and ignore "how is it that Sauron could pour his very strength into the Ring?" That'd be rather foolish, if you ask me.
So, yeah, if you simply find that the story's got a lot of stuff that's applicable to real life or that stuff in real life helps you understand the story, rock on -- just keep in mind that it's using a particular area of real life as a filter for the story, because of an assumption that the story is just a veiled telling of that area of life, that Tolkien (as far as I know) objected to. Oh, and if you do look his comments up, keep an eye out for the notion of "applicability", which was the more flexible relationship of truth and myth he advocated as an alternative in this matter.
On topic, I think we've got:
Carp = CE
Badgers = CN
Giant Sponge = NE
bugged Giant Mosquito swarms = LX (X being indetermined at this time)
Are elephants LE because the enemy harnesses them in battle (haven't seen that myself yet, so I'm hoping I'm not mixing vanilla up with Fortress Defense here)? Are they particularly famous for anything more than their danger in those situations?
The other famed animals we've got to place into LG/LN, NG, CG and NN/TN:
Unicorn (probably somewhere on the nominally "good" side of the chart, silly as it is)
Rhesus Macaque(s) (if I'm not mistaken these are somewhat social animals irl; do they fill in the third L space?)
Undead ravens
and shoot, I miscounted earlier so we have a slot for one more animal! What's another historically infamous DF animal?
