Animals Swim (Sort of) Mod
MODRabbits (and other animals) won't walk at the bottom of the sea anymore, they will float near the surface instead.
It still looks better than vanilla (imo) but you're free to remove those smaller animals from the system via SPID if you like.
This means that most terrestrial aggresive animals like wolves, bears or sabrecats won't follow you into water, unless you have a mod that modifies this behavior and allows them to follow you.
