There's no real explanation for that, although Azura could have been a cause. If not, it could be an effect of Morrowind having a vastly different environment and food. Mutations over time and all.

Then again, that's a lot of real-world logic, and this is a world of Dragons, Elves, Gods, and god-like other beings (Daedra, Ideal Masters, etc.), so I don't know how well our logic applies.
