Hi,
Since Skyrim do still have some bugs (alot have been fixed by devs and some have been fixed by players) I will trow a suggestion about a free (none cost) addon Bethesda can give us. We have alot of animals and creatures already, but I miss snakes. Bitten by snakes do not kill you, but will destroy destroy stamina at once or over time. To fix this, you have to visit certain NPC who can give you rare potions by doing quests.

Resist potions / fortify stamina potions you can buy or make self do not help against snake bites. Mine idea to have snakes wandering in the wilderness at night since daytime they sleep. Snakes do give sound (kind of rattling) so you are able to avoid them. If you manage to kill a snake, they drop pearl (from eyes), snake skin or snake tongue you can use in alchemy.

umm, skyrim is frozen over for most of the part and the areas that arent are still really cold

i wouldnt expect to find many reptiles up there, being coldblooded and all

yes theres argonians, but only in tiny numbers since they arent exactly built for cold

That's a modding idea. It's too small and insignificant for them to release by itself.

I thought it odd that the Imperial guard you escape with from Helgen mentions snakes when you leave the spider room, but you never see them in the game.
