Morrowind was [NUMINIT] weird. Oblivion had a better landscape/wildlife. Really, I don't think anyone expects all or even a quarter of the animals we're talking about here to actually show up in the game, but if Bethesda can draw inspiration from them, why not? Nature did a pretty great job creating these animals (or God, if you believe. I do).
Morrowind was wierd, but it was original and had class, nothing beats an original fantasy setting. The environment and creatures showed creativity and added a unique atmosphere to the game. Oblivion could not match the variety of Morrowind and had a bland high fantasy setting, i mean arn't you sick of it!!
I hope they do take inspiration form these wierd beasties, as they are what has formed naturally through evolution and nothing can beat that originality.
