Also, from pantheon to pantheon the gods change and sometimes even their roles, and in most pantheons the gods are the same, or very similar, but have different names - so yes those animal gods can be directly compared to the Nine (/Eight + One) but just like Shor and Lorkhan and Shezar are the same gods from different pantheon (where Shor is loved in one and Lorkhan is hated in another because of different opinions/stories etc. etc.), Orkey can be Arkay and Alduin can be Akatosh etc.
The thing is, those comparisons make me think that those pantheon comparisons are not correct :S Lorkhan and Orkey and Tu'whacca are more similar, and Alduin and Arkay are more similar, yet Orkey is Arkay and Lorkhan is Shor and Alduin, Auriel and Akatosh are more similar :/
EDIT:
Sorry if I did not make sense, hopefully you got me... It is 3:45am and I cannot sleep and blegh..
