So as I was traveling I noticed there was a standing stone on an island. After I swam to it I realized there weren't any water enemies to fight. I think it would have been cool if there were aligators or some kind of water animal to fight. I know there are were-aligator-beast so where are the aligators. There are bears and saber cats that are tough but there are no water based enemies except for the laughable slaughterfish. Are there water based spriggan type enemies?

No.

I thought that were-crocodiles are in Black Marsh. I've heard of were-sharks, but don't know where they are.

No, the waterways of Skyrim are safe as safe can be. Alligators don't live very well in places where it it snowing all day, every day.

Were-Sharks? Imagine being on that boat during an attack.

Read the tread title as "Best of NIRN". Immediately thought of a band that put all its hits onto one album. Now I'm actually thinking of forming a band and naming it that.

We'll play viking death metal.

There's no underwater combat anyway.

XD

I miss the octopus/crab men from Morrowind.....
