My Argonian made me think of this. Because of the passive, all it does is make the animation cycle faster.
So why not just give Argonians a unique swimming animation that reflects their Race and speed passive? Maybe something like how snakes slither through the water, using their tails to propel them. Maybe even add unique swimming animations to personalities as well, since some already affect walking and running.
Less seriously, have Khajiit do the doggy paddle.
