Marine life mod?

[Traveler]

You know those dead mutant dolphins and sharks that are found all over coastal area? Are there any mods that add them, and maybe some fish, to the ocean?

I haven't tested the mod and it looks lke there are few bugs with floating fishes.

If you are interested of fishing and decorations, then this may work as well.

Ms abominations adds them but maybe not in a way you want.
