Snakes?

I seem to remember being asked about snakes
but I can't find the letter and I don't remember
the exact question :)

Snake is "snákr" in Icelandic - it is declined
like "konungr".

There are no snakes in Iceland, I think there are
some in mainland Scandinavia but I don't know which
species, Keth can undoubtedly answer that.
