For reference, wolves, gnats, morbols, antlings and hippogryphs act the same way.
If they're standing in the river, it's probably the water causing you to aggro them. I aggroed a crab on my way South Bloodshore when I stepped in the water, then walked right past them after aggro wore when I stayed on the sand.
